NEEScentral Overview Data Repository Telepresence Collaboration Future Plans
Overview: NEES accounts
NEES accounts give you access to – NEEScentral data repository – Telepresence capabilities– Equipment Site NEESpops
If you do not have an account, request one now at:– https://central.nees.org/acct

Project Membership
All project members may– Create experiments, trials, and subfolders– Upload data and other documentation– Access (download/view) all parts of the project
Admins may– Delete subfolders and files– Add members to a project
NEESit Recommendation– Make MUST-SIM and/or Project IT staff the project admin to start (and include a backup
person)
Data Repository: Interim File Hierarchy
Interim File Hierarchy (cont’d)
Designed for flexibility– Unlimited number of subfolders may be created
A note on deletion– ONLY allowed by the project admins
Each NEESR and preNEESR should have its own project
Projects allow you to share data with other researchers
All NEES users may create/manage their own project
Documentation Subfolders
Exist at each level of the hierarchy
NEESit Recommendation– Place document(s) at the highest
vertical level in the hierarchy where it is still relevant across the horizontal levels
Analysis Subfolders
Pre-test simulations, design parameter studies, and post-test simulations
Include all input and output files Document any assumptions made
?
Metadata
Add metadata at the highest level– Project/Experiment/Trial– Subfolders– Files
Current metadata fields are very high level– Title/Name– Description– Objective– Start/End Date
Add documents describing metadata when existing metadata fields are inadequate
Experiments
Typically at least one (or more) experiment(s) per research group associated with the NEESR
Experiment Setup– Documents describing test setup, instrumentation plans,
designs for specimen components, etc
Trials
Minor changes to the configuration parameters defined at the experiment level
Some experiments have only 1 trial Centrifuge tests typically have
multiple trials Trial Configuration:
– Files describing specific differences in the experiment setup that make this trial unique
Trial Repetitions
Trials run multiple times without changes to setup/trial parameters
Data averaged to improve data quality Trial repetitions store multiple data sets with no changes
to setup/configuration
Trial Data
Unprocessed Data– Raw data files from data acquisition systems – sensor data, video, still images– Not always rawest form of data (or original source). Could be something
converted or exported into another format• Discourage use of proprietary formats in favor of exported formats• Where you want to start sharing from (for deriving/converting)
– Up to PI to decide what is the most basic form of data Converted Data
– Data converted to engineering units and other simple conversations– Example: Voltage to strain/curvature/displacement, converting ASCII files
from double float numbers to fixed decimal Corrected Data
– Data revised to compensate for problems or eliminate noise– Include documentations describing modifications to the data
Derived Data– Secondary and tertiary data products– Examples: plotting rotation from displacement transducers, plotting strain
profiles along a specimen axis
Data Sharing and Archiving Policy
Policies apply to both experimental and simulation data
Goals– No data lost– Ensure high quality data– Provide sufficient data/metadata to reproduce experiment
Investigators who create/collect data have a legitimate interest in benefiting from their investment of time and effort
Data timelines– Accessible to project participants as soon as it is recorded– Structured Data submitted to the permanent repository within 6
months of the end of the experiment/simulation– Made automatically accessible to the public no later than 12
months after the end of the experiment/simulation
Telepresence: flexTPS
Enables remote viewing and robotic control of live video over the internet
Recommended tool for sharing video during an experiment
Developed by Christopher Stanton, UT Austin
