GSEA Desktop v4.0.0 (Aug 2019)
Notes
- The algorithm in this version of GSEA is unchanged from the former code line and produces results equivalent to the previous version (v3.0).
- GSEA Desktop v4.0.0 requires either Java 11 or Java 8. Java 11 is preferred; we provide bundles with an embedded OpenJDK 11 JVM for Mac, Windows (64-bit), and Linux.
Improvements/h3>
- Updated for the MSigDB v7.0 release.
- Migrated code for Java 11 compatibility and corresponding better security.
- Performance improvements: we are seeing a roughly 40% improvement in our informal testing.
- Created dedicated Windows installer, Mac.app, and Linux bundle, each with an embedded OpenJDK 11 to avoid issues with the user needing to install Java. Created new command-line scripts for launching the GUI and running batch analyses so the user can avoid needing to deal directly with the more complex Java 11 command-line.
- Removed implicit dependence on out-of-date internal annotation CHIP file. Removed other special CHIP handling code to avoid conflicting with the results of the new symbol conversion from MSigDB 7.0 and better support RNA-Seq workflows. Annotations now come from the CHIP used to collapse, or else from the dataset itself (and are left untouched).
- Changed the Cytoscape integration to avoid issues with platform-specific launching issues, newer Cytoscape versions, multiple installations, custom installations, and so on. The integration now prompts the user to launch Cytoscape manually before it attempts to connect. Cytoscape 3.3+ is required.
- Switched from Ant to Gradle for builds.
- Many code simplifications and removal of unnecessary code.
- Fixed an indefinite wait cursor in the Leading Edge Tool.
