java.lang.OutOfMemoryError
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: 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
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: Use the permutation type parameter on the Run GSEA page to select gene_set permutation rather than phenotype permutation. For more information, see
