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

Note that after our publication in Bioinformatics (2011), we implemented a new method for
integrating the p-values from gene- and metabolite-based pathway analyses: Fisher's method.

IMPaLA version 13 (build June 2021)

A tutorial on how to use the IMPaLA web tool is available here.
SOAP/WSDL access to the IMPaLA functions is available through ConsensusPathDB. (direct link to WSDL file)
