“Old” ApolloWhat is Apollo?

Popular open source genome annotation editing tool

Tool for visually inspecting computational analyses and experimental evidence for genomic features and building a manually-curated consensus

Standalone Java application

Page 3: WebApollo: A Web-Based Sequence Annotation Editor for Community Annotation Ed Lee, Gregg Helt, Nomi Harris, Mitch Skinner, Christopher Childers, Justin.

In The Olden Days

Users required to download and install Apollo

Customized configurations needed to be pushed to users

Annotations saved locally in flat files

Sharing done by emailing files

Starting To Get Better

Annotations saved directly to a centralized databaseEdits made by other users not visible until you

actively reloadedPotential issues with stale annotation data

Apollo software downloaded more transparently by Java Web Start

Java versioning still an issue

Starting To Get Better

Now We’re TalkingWeb-based (runs in browser)

No software download required

Customized configurations automatically pushed to usersUsers automatically see any new data tracks

Annotations saved to centralized databaseEdit server mediates annotation changes made by

multiple users

WebApollo Framework

Page 10: WebApollo: A Web-Based Sequence Annotation Editor for Community Annotation Ed Lee, Gregg Helt, Nomi Harris, Mitch Skinner, Christopher Childers, Justin.

Web-based Client

JBrowse Javascript based annotation browserFastHighly interactive

WebApollo extensions to JBrowseProvides gestures needed for editing annotationsCommunication with the annotation editing engine

and data providing serviceHTML5 Canvas quantitative data rendering

Page 11: WebApollo: A Web-Based Sequence Annotation Editor for Community Annotation Ed Lee, Gregg Helt, Nomi Harris, Mitch Skinner, Christopher Childers, Justin.

Annotation Editing Engine

Java

Handles all the logic for editing

Edits stored persistently in the serverBerkeleyDB JE for fast accessAble to restore data if either client or server

crashes

Once annotators are satisfied with annotations, they are stored in a centralized Chado database

Per-sequence (contig, chromosome, etc.) user permissions (none/read/write)

Page 12: WebApollo: A Web-Based Sequence Annotation Editor for Community Annotation Ed Lee, Gregg Helt, Nomi Harris, Mitch Skinner, Christopher Childers, Justin.

Multiple Client Synchronization

Comet modelServer pushes annotation updates to all clients

in real time

Page 13: WebApollo: A Web-Based Sequence Annotation Editor for Community Annotation Ed Lee, Gregg Helt, Nomi Harris, Mitch Skinner, Christopher Childers, Justin.

Enabling WebApollo to access as many types of genomic data as

possible

Efficient access to public data from UCSC, Ensembl, and GMOD Chado databases

Unified strategy like DAS is preferred

Solution: Trellis, a DAS server framework that: Supports modular back-end plugins

Poka Trellis plugin for direct UCSC database access

DAS plugin to support Ensembl servers

Supports modular front-end content formats JBrowse JSON plugin
