java.lang.OutOfMemoryError (GSEA v1)
Problem: On the Mac, you can run GSEA from the command line, but when you attempt to use the GSEA application from the desktop you receive errors similar to the following:
Full Error Message ----
na
Stack Trace ----
- of exceptions: 1
null------
java.lang.OutOfMemoryError
Solution: Corrected in GSEA v2. In GSEA v1, this is a memory issue with the gsea installer on the Mac. As a workaround, use the following command to launch the GSEA application rather than double clicking the icon:
java -Xmx1800m xapps.gsea.Main
java.lang.NullPointerException (GSEA v1)
Problem: By default, a gene set enrichment analysis uses phenotype permutations. If you have too few samples for phenotype permutation, the following error occurs:
Stack Trace ----
- of exceptions: 1
null------
java.lang.NullPointerException

Solution: Corrected in GSEA v2. In GSEA v1, use gene_set permutation rather than phenotype permutation. For more information, see the description of the Permutation type parameter on the Run GSEA Page in the GSEA User Guide.
