This page was intended to capture  "gotchas" and "confusions" that users encountered in using the V2 software. These observations can now be captured in Bugzilla as documentation and/or software enhancements.

CLS file problem

CLS file with four classes which was loadable to GSEA ver1 does not load anymore:

It loads after changing it to:

==Java Heap Space error===

On a 2GB Windows XP workstation with no other than GSEA applications running I am getting:

java.lang.OutOfMemoryError: Java heap space

using all.may_2006.symbols_mapped_to_Mouse430_2.gmt, CLS mentioned above + expression file (derived from 22 CEL files of Mouse430_2 platform), 100 permutations .

1) Can I somehow increase available memory, i.e. by running it on a command line?

2) Any other ideas how to complete the job?
