GSEA Desktop v4.0.1 (Aug 2019)

Miscellaneous bug fixes:

  • Fixed an issue with Collapse Dataset that was at-odds with the MSigDB recommendations for symbol remapping.
  • Fixed an issue with the Chip Chooser when FTP access is not available.
  • Fixed an issue with the Leading Edge Tool when launched from Java Web Start JNLPs.

GSEA Desktop v4.0.0 (Aug 2019)

The GSEA v4.0.0 release includes a number of improvements and bug fixes, including:

  • Updates for the MSigDB v7.0 release.
  • Updates for compatibility with Java 11 and the (free) OpenJDK version of Java.
  • New options for downloading and launching the application:
    • Windows installer, Mac app, and Linux bundle, each with an embedded OpenJDK Java 11, which means no separate Java installation is needed.
    • Command-line scripts for running batch analyses, which means users no longer need to enter Java commands directly. Note that a separate Java 11 installation is required.
    • Note: Launching the application using Java Web Start still requires a separate Java 8 installation.
  • Miscellaneous performance improvements and code simplifications. These add up to a roughly 40% improvement over v3.0 in our informal testing.
  • 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.
  • Fixed an indefinite wait cursor in the Leading Edge Tool.
  • Updated the annotations and processing code used by the GSEA application to match the new symbol conversion procedure used to create MSigDB 7.0 (see the MSigDB release notes)
