I am trying to visualize a GSEA analysis I conducted using the Broad Institute's GSEA Enrichment Map Visualization, however I get the following error and am not sure what the issue is: any help would be greatly appreciated.

  • $\begingroup$ Could you please explain the steps to reproduce this error? What data did you load, the settings and steps to connect to Cytoscape... and what do you expect from us. To me it seems like we should debug the GSEA software in order to solve this problem... $\endgroup$

This is a tough one, because the only relevant lines from your GSEA debug log were these two:

DEBUG - http-outgoing-4 << "Failed: empty String"
DEBUG - http-outgoing-4 << HTTP/1.1 500 Internal Server Error

My recommendations to you at the time would've been

  1. try closing all the programs, restarting them, possibly rebooting and restarting them, and even analyzing a completely different set of data to see if you get the same results, —or—
  2. update to the latest Java 8, reinstall Cytoscape 3.7.whatever and the EnrichmentMap plugin from scratch, and re-download GSEA, —or—
  3. lastly, try reinstalling everything on a completely different machine/OS and see if you get different results (e.g., try on a Mac or Linux if you had problems with Windows originally, or vice-versa)

I know that's lame, but sometimes that's how you solve weird computer errors, when the error message the application itself gives you is non-specific and unhelpful.

If you had seen the error message

None of the gene sets have passed the filter. Try relaxing the gene set filter parameters.

in the GSEA application logs, then you would've had the problem described in EnrichmentMap's GitHub issue #358, and the solution would be to use less stringent p- and FDR Q-value cutoffs, as prescribed in the "Tips on Parameter Choice" section of the EnrichmentMap documentation.

My problem was that GSEA's default cutoffs (p-value < 0.005 and FDR Q-value < 0.1) were entirely too stringent for my results set, and using the "Very permissive" settings of p-value < 0.05 and FDR < 0.25 from the documentation solved it for me.

Hopefully this benefits someone who ends up here after googling for "Unable to create Enrichment Map:Internal Server ErrorResponseEntityProxy," which is just a stupendously unhelpful error message when "None of the gene sets have passed the filter" is actually what went wrong. Maybe go thumbs-up this comment in the EnrichmentMap issue tracker, if you think the maintainers need to work on that.
