IMPaLA: Integrated Molecular Pathway Level Analysis

pathway over-representation and enrichment analysis with expression and / or metabolite data

genes/proteins
- example input for over-representation analysis
- example input for enrichment analysis

paste genes or proteins below


or upload a file with genes or proteins


optionally, provide genes/proteins background
for over-representation analysis


metabolites
- example input for over-representation analysis
- example input for enrichment analysis

paste metabolites below


or upload a file with metabolites


optionally, provide metabolites background
for over-representation analysis



choose analysis type:
  pathway over-representation analysis
  Wilcoxon pathway enrichment analysis


or clear the form
New: a new method has been implemented for integrating the p-values
from gene- and metabolite-based pathway analyses: Fisher's method.
