Customer Correlation (CUSCOR) V5.2 forWin95/NT - a user guide

Introduction and overviewThis help file will help you to use CUSCOR. However, the intelligent application ofCUSCOR relies upon the users good engineering judgement - CUSCOR cannot supply thiscommodity and makes no attempt to do so - it is an aid to good engineering practice, not asubstitute for it. This help file is not a substitute for thorough training in CUSCOR either -CUSCOR is capable and complex and all users will benefit from formal CUSCOR training,even those that have used DOS COR.

The Customer Correlation module synthesises a target signal using various amounts of anumber of sample .CYH signals.

The synthesis can be achieved automatically, manually, or with a combination of both. Anumber of channels can be in use, i.e. using sets of target and sample signals, but only onechannel is actively correlated: the effect of the solution mix however is immediately shownfor the other channels.

Colour is used extensively in the module to clarify the information displayed, which can becomplex. Three dockable windows provide a visual display of the solution and allow differentsolutions to be instantly assessed.

It is possible to plot the displays: it is also possible to save a session at any point as aCorrelation project file, and recall it either on starting COR or from within a CUSCORsession.

Note that the technical theory behind CUSCOR is outlined in the help file CORTECH.HLP.

Section 1 - The workspace

Section 1 - The workspaceThe workspace appears when CUSCOR is first run. It consists of a menu system and aseries of toolbars that contain icons. It also has three windows in the main area of theworkspace.

Source data window (left) Mix solution window (middle) Target datawindow (right)

Features and operation of the workspace windows

Gripper bars are used to resize areas.

The 'docking diamond' can be used to dock or undock a Window if clicked.If clicked and held it calls up a menu that allows you to dock to the top, left,bottom, right, etc.

Docking windows are used for toolbars, and Source and Target windows.Docking windows have 3 states:

1. Docked to the main application window. When docked to the left, right ,top or bottom of the main application window, the window will have agripper bar. This state has the advantage that is always fully visible and


Page 5 of 61

cannot be overlapped by other windows. 2. Floating. When in a floating state the window can live outside of the main

application window. This state has the advantage of being displayed aboveall the other windows and is thus visible at all times. To prevent the floatingwindow from automatically docking to the main application windows, theCTRL key must be pressed whilst moving the windows.

3. Floating in the main application window. When in this state the windowbehaves as other windows in a Multiple Document Application. Thewindow can be resized, maximised, tiled, cascaded and moved, but cannever leave the main application window area. Whilst the window is in thisstate and workbook mode is on, a tab will appear at the bottom of the mainapplication window area, allowing quick access to this window.

Section 3 - Preparation - Adding Target and Sourcedata

Before a mix can be created and a correlation exercise carried out there mustexist some Target and Source Data.

There are 4 ways of adding Source and Target data to the project.

Manually input (manually specifying source and target) Importing CYH file(s). Importing SMH file(s). Importing MIX file(s).

Manual input

Manual input of data means that each individual item of data is entered usingthe application menu and / or the menu generated by clicking the right mousebutton whilst over the Source Data Window or the Target Data Window. Inpractice large amounts of data will be involved with each project and themanual input of data will be rarely used.

Add a Source data objectA Source data object is a collection of related Sample Data. For example avehicle may be fitted with several data collecting sensors and driven acrossnumerous surfaces on a particular test track. With the sensors being constantthroughout the tests the data is therefore related. Identical test methods andtype of data may have been collected from a different test track and are thusnot directly related to the first suite of data.A Source data object can be added to the Source Data Window by eitherselecting Source\Add Source from the main application menu, or by selectingAdd Source from the menu generated by clicking the right mouse button in theSource Data Window.

Name This is the name of the Source data object.Set Path This option is primarily for use when using the same set

of parameters for a test, but using different source datawhich may be stored in a different location. This removes


Page 16 of 61

the need to go into each individual sample and changethe root directory for the data. This field is greyed outwhen there are no samples defined for the Source dataobject.

Path toData

This is the drive and directory root path used to set theroot path for all the sample(s) which may exist for thisSource data object.

Browse Pressing this will bring up a drive and directory browsescreen which allows a directory to be selected. Onleaving this screen the directory will be entered into thePath to Data field.

OK Accepts the current set-up.Cancel Abandons the current settingHelp Accesses the on line help

The Source name must be unique to the project and application will produce awarning message if this is not adhered to. The new Source data object will beadded to the end of the list of Source data objects in the Source Data Window.

Add a Sample to the Source Data WindowA Sample is a collection of data collected from a specific stage of a test. Forexample a vehicle may be fitted with several data collecting sensors and drivenacross numerous surfaces on a particular test track. A sample in this casewould represent the data collected for ONE particular surface or event.

A Sample data object can be added to a Source data object by either selectingSource\Add Sample from the main application menu, or by selecting AddSample from the menu generated by clicking the right mouse button in theSource Data Window. The currently selected item in the Source Data Windowmust be a Source data object.


Page 17 of 61

Name This is the name of the new Sample. For examplePAVE

Path to Data This field defines the path of the family of datastored in the Channel data. For example the datafiles may be PAVE01.CYH through PAVE20.CYH.

Browse Pressing this will bring up a drive and directorybrowse screen which allows a directory to beselected. On leaving this screen the directory will beentered into the Path to Data field.

Units of SampleLength

This field contains the units in which the Sample wasmeasured. For example if this is a Target Samplethen the units could be miles that the customervehicle was driven during the real world application.

Sample SetLength

This field defines how far the sample was tested /driven. The number is expressed as an amount ofUnits of Sample Length. For example 50000 milesdriven for a customer vehicle.

Events Name For some samples the data may be best describedas a number of events. For example Kerb Strikes.The final solution can then be expressed in terms ofevents as well as Units of Sample Length, ie x KerbStrikes.

Number ofEvents

This field defines how many events took placeduring the collection of the data.

Which Axis toKeep

If the x-axis is chosen then the (8/16/32/64/128) binsrelating to each x bin in the CYH data file(s) will besummarised into one bin, which will be an x-axis inthe solution.

Mean ofLargest Cycle

This is used purely for cycles files. The mean of thelargest cycle is the most significant one and will bethe one that is used for the 65th bin.

Average valueof lost axis

With this option the average value for the axis whichis lost is calculated, i.e. if correlating on thehistogram x-axis then the average of the y-axis isused for the 65th bin.


The Sample name must be unique to the Source data object to which thesample is being added, but not necessarily unique to the project. For exampletwo similar test tracks could have the same surface name, e.g. pave01 andpave01. The application will alert the user if a sample name already exists, butthe new Sample will still be added to the end of the list of Samples in theSource data object.

Adding Channel data to the Source Data Window

A Channel data can be expressed as data collected from a particular sensorfitted to vehicle throughout an entire test. For example the data collected from aFront Wheel Suspension.

A Channel data object can be added to a Sample by either selectingSource\Add Channel from the main application menu, or by selecting AddChannel from the menu generated by clicking the right mouse button in the


Page 18 of 61

Source Data Window. The currently selected item in the Source Data Windowmust be a Sample data object.

Number This is the Channel number of the data. This numbermust be unique for each Sample.

Name This field is optional and may be used on thegraphical display in the solution.

X-Axis Title This field is optional and may be used for displaypurposes.

X-Axis Units This field is optional and may be used for displaypurposes.

Y-Axis Title This field is optional and may be used for displaypurposes.

Y-Axis Units This field is optional and may be used for displaypurposes.

AverageDescriptor

This field is used if the Average value of lost axishas been selected for the Sample.

Filename This is the name of the actual data file in which thecollected data is stored.

Browse Pressing this button will bring up a standardWindows file open dialog allowing the data file tobe found. On leaving the name will be placed in theFilename field.


The Channel number must be unique to Sample. The application will produce awarning if this is not adhered to.

Add a Sample to the Target Data Window


Page 19 of 61

A Sample is a collection of data collected from a customer vehicle that hasbeen in use in the real world for a period of time. For example a vehicle may befitted with several data collecting sensors and driven for a period of time or for aparticular distance in a real world situation.

A Sample data object can be added to a the Target Data Window by eitherselecting Target\Add Sample from the main application menu, or by selectingAdd Sample from the menu generated by clicking the right mouse button in theTarget Data Window.

See Add a Sample to the Source Data Window for the visual method anddescription for entering Sample details.

The Sample name must be unique to the Target Data Window. The applicationwill produce a warning message if a sample name already exists. The newSample will be added to the end of the list of Samples in the Target DataWindow.

Adding Channel data to the Target Data Window

Channel data is usually data collected from a particular sensor fitted tocustomer vehicle throughout the in-use period, e.g. the data collected from aFront Wheel Suspension.

See Adding Channel data to the Source Data Window for the visual methodand description for entering Channel details.

A Channel data object can be added to a Sample by either selectingTarget\Add Channel from the main application menu, or by selecting AddChannel from the menu generated by clicking the right mouse button in theTarget Data Window. The currently selected item in the Target Data Windowmust be a Sample data object.

The Channel number must be unique to the sample, otherwise the applicationwill produce a warning.

Copying and pasting Sample/Channels and individual Channels

To add another channel repeat the above procedure OR click Source\CopyChannel which copies a channel to CUSCOR's internal data clipboard.

Then click Source\Paste Channel (or control v) to pop up the Paste Channelwindow which is functionally the same as the New Sample window. Edit theparameters of the copied channel and click OK to complete the paste.

To copy and paste an entire sample, including all its channels, click on asample icon and click Source\Copy Sample.

Importing CYH file(s)

Sample and Channel data should in theory be stored as families of data on theusers storage medium. The CYH wizard will search drives and subdirectories


Page 20 of 61

and recognizes these as families of data, making the entry of large amounts ofdata an uncomplicated affair.

The data entry for large numbers of files can be made even simpler by the useof extra details keywords. The import process checks for the existence ofcertain Extra Details Keywords in the individual CYH files. The process will usethe first file in the list to set Sample properties using the following keyword /value pairs.

Keyword Value Sample Property$SAM_UNI Alphanumeric Units of sample length$SAM_LEN Numeric Sample set length$SAM_EVS Alphanumeric Events name$SOU_AXI X or Y (any case) Which axis to keep$SOU_MEA M or A (any case) Mean value to be used

If the following keyword/value pairs are present in the individual files then theywill be used to set the corresponding channel properties:

Keyword Value Channel Property$YTITLE Alphanumeric Channel name$SOU_DSC Alphanumeric Channel description

1. Click File\Import CYH File(s) from the main application menu

Three parameter .CYH files can be used as CUSCOR's source or target data.The following procedure applies to both. To import .CYH files:

This brings up the Import CYH file(s) Wizard that leads you through theimportation process.


Page 21 of 61

The first action is usually to use the Change Search Directory button so thatCUSCOR points to the relevant drive and root directory that contains the familyof .CYH files.

When CUSCOR is looking in the right directory click the Search Now buttonand CUSCOR will list all the generic families of .CYH files. In the aboveexample the family named STON actually consists of 5 files - STON01.CYH,STON02.CYH, STON03.CYH, STON04.CYH and STON05.CYH.

Each family will contain a number of individual .CYH files, one per channel ofdata, as indicated by the nChannels column above.

Note that you can then click the Change Search Directory button and addanother directories contents from another drive to the list. CUSCOR retains theresults of each Search in the list until you click Clear List.

Select the CYH families by clicking on their names. Use shift click to select ablock of families. Use CTRL click to individually select families from the list.

Click Next when you have chosen the families you want.

2. Selecting source and target samples.

The next stage of the import CYH Wizard allows you to specify whether the filesyou have just chosen are to be included as Source data or as Target data.


Page 22 of 61

Note that it is permissible for a family to be included as Source data and Targetdata. A real world application may involve correlating one test track againstanother.

If the family is to be imported as Target data then a Finish button will appearand the name of the family will be used as the Target sample name. If thesample name exists in this case then an unique number will be appended to thesample name and left to the user to alter this.

If the family is to be imported as Source data then the Next button has to bepressed to progress to the final stage of the CYH Wizard.

3. Import CYH Wizard - Naming the Source.

The third stage of the CYH wizard applies to families of data that are beingimported as Source data. The name of a Source (ie Collection of Sample data)is prompted for. This name must be unique to the project.


Page 23 of 61

By default CUSCOR will give it the name of the first family selected in 3.above.

4. Specifying CYH sample details - Important Note

You have the option of manually filling in the axes titles for each .CYH file byexpanding the samples or target icon tree and then clicking on an individual.CYH file.

However, you must fill in the Sample Set Length part of the samples icondetails. If CUSCOR does not know the distance represented by the .CYH filesin the sample then it cannot achieve a solution.

To enter the Sample Set Length, click on the samples or target icon to pop upthe Samples Properties window as shown below.


Page 24 of 61

Type the distance in the Sample Set Length field, the Units of Sample Lengthare optional.

Importing SMH files

SMH files were produced by the now obsolete nSoft 'Summarise Histograms'module, SMH. The SMH wizard will search drives and subdirectories andrecognises the families of SMH data, making the entry of large amounts of dataan uncomplicated affair.

Importing .SMH files is therefore a backwards compatibility feature.

1. Click File\Import SMH File(s)

This brings up the Import SMH Wizard that leads you through the importationprocess.Please note that SMH data can only be bought in exclusively as Source orTarget data each time wizard is executed.

The first action is usually to use the Change Search Directory button so thatCUSCOR points to the relevant drive and root directory that contains the familyof .SMH files.

2. Searching and Selecting a SMH Family of files

When CUSCOR is looking in the right directory click the Search Now buttonand CUSCOR will list all available generic families of SMH files. For examplein the above example the family named TRAX actually consists of 5 files -TRAX01.SMH, TRAX02.SMH, TRAX03.SMH, TRAX04.SMH andTRAX05.SMH.

Each family will contain a number of individual SMH files, one per channelof data, as indicated by the nChannels column above.

Note that you can then click the Change Search Directory button and addanother directories contents from another drive to the list. CUSCOR retains theresults of each Search in the list until you click Clear List.

Select ONE SMH family by clicking on its name.

Click Next when you have chosen the family you want.

3. Source or Target?

The next stage of the import SMH Wizard allows you to specify whether thefiles you have just chosen are to be added to the Source or Target data.


Page 26 of 61

Note that it is permissible for a family to be included as both Source data andTarget data; a real world application may involve correlating one test trackagainst another.

Pressing the Next button will proceed to the next stage of the wizard. If theSMH files are to be added to Source data then stage 4 of the wizard will appearnext. If Target has been selected then stage 4 will be missed out proceeddirectly to stage 5.

4. Naming the Source


Page 27 of 61

This is the name of the new Source data object to create the data in.

5. Selecting the Sample(s) to use

The final stage of the wizard allows selection of the samples / channelscontained within the SMH file that is to be imported.

Using SHIFT and left mouse button click will select a block of samples /


Page 28 of 61

channels.Using CTRL and left mouse button individual samples / channels can beselected.Pressing the Finish button will finalise the selection and import the data.

6. Specifying Sample details - Important Note

Sample details should be carried over from the original .SMH file.

Please note that when importing SMH file(s) there may be some duplicateinformation contained within them. In this case the application uses intelligenceand appends a unique ID to end of the duplicate name(s). For example aTarget sample with a name of DRIVER may be renamed DRIVER~01 if thename has been found to already exist in the project.

Importing a MIX file

A .MIX file is the output of the previous release of the module COR. Each filecontains enough data about each sample and channel from a project to providea solution. However because this data is summarized data of the original datafile(s) only a limited amount of processing can be achieved.

Because MIX files contain completed solutions there is no need for the mixwizard.Importing one or more MIX file(s) involves using the standard Windows fileopen box. More than one file can be imported.

Please note that when importing a MIX file there may be some duplicateinformation contained within it. In this case the application uses intelligence andappends a unique ID to end of the duplicate name(s). For example a Targetsample with a name of DRIVER may be renamed DRIVER~01 if the name hasbeen found to already exist in the project.

The Channel Details Wizard


Page 29 of 61

This wizard allows generic channel details information to be defined and applied toall or a selection of sample data.

1. Set Channel Details : Page 1 of 3

A list of ALL the samples that exist in the project are displayed here, regardless ofwhether they exist within the Source data window or the Target data window. Oneand only one sample must be selected. The channel details defined for this samplewill be used for default values on the next screen.



Page 30 of 61

A grid displaying all the channel information defined for the selected sample will bedisplayed here. Pressing the right mouse button on a field will bring up a menuwhich allows data to be copied to other channels in the list.


Select at least one sample to copy the channel details to.

Section 4 - Auto Correlating the source files to thetarget files

Section 4 - Auto Correlating the source files to the target files Note that before a correlation can be attempted the source and target datamust have been specified as explained in Adding Target and Source Data.

COR summarises the input data to 16 amplitude bins (plus one mean), usingautomatic scaling to maximise bin use and accuracy. This totals either four,three, two or one .CYH bin(s) into one COR bin, depending on the first and lastbins containing a value over zero in the target and sample data.

Each channel is scaled separately. To make visual comparisons meaningfulthe target and sample data is all normalised to the same length, for example100,000 miles, or whatever is the length of target signal being correlated to.Log scaling is used on the Y-axis for all displays.

The last bin is either Mean or Average, this being selected from within COR.

The Average option is for histograms holding other than cycles data, and showsthe average value for the lost axis, i.e. the Y-axis if binning to X-axis.

The Mean option is for cycles histograms, and is the most positive mean in thelargest amplitude bin, i.e. the mean of the most damaging cycle.

There is a problem inherent in attempting to summate cycles histograms,relating to the potential loss of the largest cycle, particularly when the means ofthe larger cycles are very different. Include the mean of the largest cycle in thecorrelation as the most satisfactory method of handling this, but even thiscannot completely solve the problem.

Automatic Correlation attempts to match the number of cycles in the 16 bins inthe target signal by summing differing proportions of samples, each naturallybeing compatible with the target, i.e. having the same bin sizes etc. Themean/average is also matched.

Automatic Correlation is achieved using Simplex Linear Programming, iteratedto achieve the narrowest error bounding possible. The use of LinearProgramming allows the imposition of sophisticated constraints: the accuracyrequired for different bins and the mean can be varied; the user can boundpermitted sample use, for instance insisting that a minimum of 10% andmaximum of 50% of the solution be 'Pave'.

The Mix Wizard - Correlation is achieved via the use of the Mix Wizard in thefollowing manner:

The Mix Name is the name of the particular Correlation that is going to beperformed on the selected data. This name is used to identify this unique set ofsolutions from other solutions in the Mix Solution window.

Select the NEXT button once the Mix Name has been entered and one ormore channel(s) have been selected to progress to the next stage.

4. Setting the length of target to match to

This is the length of the target sampling that you wish to recreate with thesample data.


Page 35 of 61

Select the FINISH button once the Length of Target to match to has beenentered and the MIX wizard process.

5. Achieving solutions

When steps 1 to 4 above have been completed a mix icon will appear in theMix Solution window.The target and source icons tell you what the mix is comprised of and are forinformation only, except for the sources colour codes which are used in thedisplays.

To carry out a correlation you must first expand its tree so that it looks like this.


Page 36 of 61

Main Channel icon

- Double click the left mouse button on the main channelicon. The Main Channel Solutions Details window will appear.


Page 37 of 61

Click the Calculate button and COR will use its simplex linear programmingalgorithms (see COR's technical overview help for details of the algorithm) inan attempt to achieve a solution.

One of two things could happen now. Either a solution will be found, or nonecan be achieved, as indicated in the status box.

If no solution has been achieved then changing the settings in the Error Bounds- Bin Accuracy window and re-calculating may achieve a solution.

Either way, you must repeat the above procedure for each of the channels.

Manual correlation can commence from a previous solution (for example fromAutomatic Correlation) and works by adding or subtracting amounts of samples,the effect on the solution being immediately displayed for all channels on theStrata Plot.

Printouts of thumbnail plots, and details and solution grids, can only be made ifsolutions have been achieved. See File\Print for details of the Print Wizard .

The Bin Settings button (Error Bounds - Bin Accuracy)

If error bounds is set to high (H) then COR will undergo more iterations in orderto get closer to a solution. If set to low there will be fewer iterations. COR mustbe told when to stop iterating otherwise its simplex linear regression algorithmswill continue iterating indefinitely.

The accuracy's required for each of the 16 bins plus the mean can beindividually set, so the correlation is tailored to concentrate on important areas


Page 38 of 61

and take little account of unimportant areas. The initial default is Normal. Clickon the L, N or H under each bin to set the accuracy's individually.

The maximum error bounds for 'Normal' accuracy are -67% to +200%, thoughwhen a solution is found it is normally within a smaller error band. 'High'accuracy halves the Normal error band whilst 'Low' accuracy multiplies it byfour.

Note: There is a minimum error which is always allowed, to avoid consistentlynull results on low value bins. This minimum corresponds to a value of 1 in theoriginal target signal. For instance if the original signal were taken from a10,000 mile sample and the target correlation mileage were 100,000 then thesingle cycle (or whatever) would translate to 10 cycles error which would beallowed in the solution, whatever the error band. However this minimum error isstill subject to the 'High' and 'Low' accuracy modification.

The Sample Usage button (Bound sample display)

This allows the user to set a maximum or minimum percentage of the totalsolution mileage for the currently selected sample, or block it from usealtogether in Auto Correlation. For instance, 'Pave' could be blocked from useor limited to a maximum of 20% and a minimum of 1% of the solution mileage.


Page 39 of 61

You can change the sample being constrained by double clicking in the MinUse or Max Use Field and typing a percentage value, or using the spin dials.

Note: The user can have up to 30 max/min constraints, and is advised if thelimit is reached. A sample not used (no check in the check box) will not haveany of it's max/min constraints taken into account.

'The 'Use' check boxes block/unblock a sample from use in Auto Correlation.

Section 5 - The graphical display and modification ofauto correlations

Section 5 - The graphical display and modification of auto correlationsThis section explains how to display the components of COR's solution files.The display windows are not just for viewing purposes though; they can also beused to manipulate the solution and produce 'manually adjusted' (optimised ormodified) solutions.

There are 4 display windows available;

1. Thumbnail plots2. Main display plots (made of 3 sub plots)3. Channel solution details grids4. Overall solution details grids

Double clicking on any of these icons will toggle its graphical display orspreadsheet on/off.

The histogram plotIt is a clipped histogram view of the difference between the target and the solution. If asolution is manually adjusted the view will also show the differences between target andmanually adjusted as they can be set to be different colours (as above).

The blocks above the 0 line indicate over-testing.

The blocks below the 0 line indicate under-testing.

The non colour filled blocks indicate that the % error is positive but could not be calculatedbecause the divisor is zero, e.g. the target = 0 but that there is some solution, which willmean divide by 0 and infinite error.

Clipping values can be set in the Graph Settings window and they can be set to % error oractual error. In the above plot the clipping is set to 1000. If an error is more than 1000 thenthe histogram bar will protrude slightly above the 1000 line. If an error is 1000 then the top


Page 46 of 61

of the histogram bar will lie exactly on the 1000 line.

Note that it is an engineering decision as to whether or not large 'errors' are acceptable.

The strata plotThis plot illustrates the contribution of each of the channels ticked in the channel solutiongrids check boxes, to the overall solution, or manually adjusted solution. If a manuallyadjusted solution exists then that will be displayed in the plot.

Each coloured strata represents a samples contribution towards the solution plotted in %terms per bin.

Its X axis is log scale.

This plot is linked to the Overall Solution Grid in that if the Contrib column's check box isticked then the contribution of that sample to the solution is displayed.

The number of samples contributions can also be limited to the n most contributingsamples by setting the number of samples on the in the Graph Settings window.

The target and solution plotThis is the log to the base 10 plot showing target and solution. If a solution is manuallyadjusted the view will also show the difference between the target and manually adjustedsolution.

This plot is linked to the Overall Solution Grid in that if the Contrib column's check box isticked then the contribution of that sample to the solution is displayed on this plot. Ifgreater than 1 check box is ticked then the plot becomes a cumulative contribution to thesolution, if they are all checked then it becomes the solution.

The Channel Solution gridThis is a numerical representation of the Main Plot display. It is for information only andcan not be edited.

The channels relate to the main display in the following way.


Page 47 of 61

The Target, Solution, and Tweaked columns are visually displayed on the Log targetversus Solution plot (the middle plot).

The % error solution and tweaked solution columns are displayed on the Error Histogramplot (the top plot).

The Strata Plot displays the Tweaked column, or the Solution plot if no tweaks have beencarried out.

A use for the Channel Solution Grid is to compare it to the main plot, because errors on themain plot can be explained by looking at the underlying numbers shown on the channelsolution grid.

Changing main display plot colours

To change the colours of any of the Main Display plots components go to the menu systemand click Options\Set Default Colours to pop up this window.


Page 48 of 61

If the colours of the plot components in upper case (the top 6) are changedthen the changes will be reflected in the plots as they are made. The lowercase plots (Sample 01, etc.) are the current defaults for the samples/surfaces,but they are assigned once only when the solution was created. If you want tochange the colours that are used on the strata graph then look at The SamplesColour palette.

The Overall solution gridThis is a numerical representation of the top graphic of the channel solution plot..

Ticking the Contribution (Contrib) check boxes causes the contribution of the tickedchannel to be displayed on the Channel Solution Plot.

Manually adjusted solution values may be modified either by typing a new value or byactivating the spinning dial by double clicking in the box and spinning the values up ordown.

Note: manually adjusted solutions are indicated on the channel solution plots as a blueline.

Monitor sizeCOR's inputs and outputs.COR.CYH.MIXData directories - the Importance of preparationTraining

Monitor sizeCOR can be viewed on any monitor, but because its use often involves many windowsbeing open at once, it is recommended that you use a monitor of at least 17 inches or 42.5cm.

COR's inputs and outputs.COR.CYH.MIX

.CORThis is the new file format for the Windows port of COR.

.CYHA cycles histogram. They are 3d files of test data.

A group of DAC files e.g. 20 files from 20 accelerations, can be summarised into 20 CYHfiles that could represent (for example) the test vehicle running over PAVE or overcobblestones.

Each CYH files summarisation consists of, bins, each bin being the total of the values of anX or Y axis bin, plus a extra bin whose value is either the mean (cycles histograms) oraverage (other histograms).

CYH files used to have to be 64x64 bins but can now be a combination of any of thefollowing:

e.g. 8x128.

The previous release of COR summarised the files into a .SMH file in module SMH, butCOR 5.1 handles this step internally and module SMH has been removed from the productrange.

.MIXMIX files are the old DOS format file type. They contain details of the original target andsource .CYH files, including their locations, distances, units, etc. and the solution achieved


Page 50 of 61

for them.They do not contain the .CYH files themselves, although this should not matter unless theybecome invalid and a new solution was therefore needed.

Data directories - the Importance of preparationIt cannot be stressed too much the importance of planning prior to collectingdata.When data collection commences it may acquire thousands of files which canbest be imported into nSoft and COR if the files have been automatically sortedinto directories that contain related data.

So: Plan the directory structure into which data will go very carefully.Remember, that thousands of DAC files may be collected and they will need tobe despiked and reduced to .CYH format. Standard macros can be used to dothis and they need standardised directory naming and organisationconventions.

TrainingThis user guide will hopefully help you to use COR - however it is a highlycapable and complex piece of software that relies heavily on the skill andjudgement of the user. It makes sense to undergo training on COR before youuse it and nCode will be happy to provide training either at nCode or at yourown premises.

Frequently Asked Questions

Frequently Asked Questions

Can COR for Windows re-use old COR MIX files?


Page 51 of 61

On selecting the histograms, how does COR build the classification of different events andsamples?

Do all the source inputs need to be specified in the same units of sample length?

Can I go back to the initial solution after I have made changes to the contributions?

How do I switch on different solutions?

How does each 'event' 'contribute' to the solution?

How is the graphical contributions plot composed?

What do the empty blocks in the Main Plot Solution represent?

Which are the Target and Solution curves?

Can I change the colours of the contributions graph?

Yes, click the right mouse button on the plot to popup a colour palette from which you can choose acolour.

Can I go back to the initial solution after I have made changes to thecontributions?

You need to manually reset the modified values back to their starting values and calculateagain. You can also exit COR without saving and restart but only if you have not saved anychanges.

How do I include or switch on different contributions?

Changing the value of the 'Adjusted column in the solution grid of the Main Channel. Byleft clicking once in the value box that contribution will be activated and can therefore bechanged. A new solution is created and displayed alongside the original solution, bothgraphically and numerically.

How does each 'event' 'contribute' to the solution?

On a bin basis.

How is the graphical contributions plot composed?


Page 52 of 61

It is built according to the order in which the eventswere selected, i.e. on a cumulative basis.

What do the empty blocks in the Main Plot Solution represent?

They represent data that cannot be plotted, but whichis out of range. The non colour filled blocks indicatethat the % error is positive but could not becalculated because the divisor is zero, e.g. the target =0 but that there is some solution, which will meandivide by 0 and infinite error.

Can COR for Windows re-use old COR MIX files?

Yes. Use the File\Import option to import .MIX, .SMH, and .CYH files.

Do all the source inputs need to be specified in the same units of samplelength?

No, you can have kms, laps, miles, or even 'open and close a door', etc. with theircorresponding Target equivalents.

On selecting the histograms, how does COR build the classification ofdifferent events and samples?

The program will identify the name stem of each of the events and samples files. It willscan the stems from left to right and identify matching stems, and will label the stem as anevent. It will include all of the different channels under that event.

Which are the Target and Solution curves?

They are the curves plotted on the thumbnail plot .
