Enrichment Map g:Profiler Tutorial


This quick tutorial will guide you through the generation of an Enrichment Map for an analysis performed using g:Profiler (Functional Profiling of Gene List from large-scale experiments)

To run this tutorial:

Description of the tutorial files contained in the gProfilerTutorial folder:


Step 1: Generate g:Profiler output files

  1. Go to g:Profiler website - http://biit.cs.ut.ee/gprofiler/

  2. Select and copy all genes in the tutorial file 12hr_topgenes.txt in the Query box

  3. In Options, check Significant only, No electronic GO annotations

  4. Set the Output type to Generic EnrichmentMap

  5. Show advanced options

  6. Set Max size of functional category to 500

  7. Set Significance threshold to Benjamini-Hochberg FDR

  8. Click on g:Profile! to run the analysis

  9. Download g:Profiler data as gmt: name

  10. Download the result file: Download data in Generic Enrichment Map (GEM) format

Note: repeat these steps for the 24hrs time-point and the file 24hr_topgenes.txt

Step 2: Generate Enrichment Map with g:Profiler Output

g:Profiler output files gProfiler_EM.zip

Step 3: Examining Results

gProfiler EM Result

  1. Node size corresponds to the number of genes in dataset 1 within the geneset
  2. Colour of the node corresponds to the significance of the geneset for dataset 1.
  3. Edge size corresponds to the number of genes that overlap between two connected genesets.
