Hi Bioconductor users, I am fairly new to bioconductor. I have been given some differentially expressed genes (181) and I need to find the pathway analysis. What kind of informations are needed for pathway analysis and which packages are the best to analyze it. Thank you very much for help in advance.

Being new to Bioconductor, you might be best served if you examined functional enrichment of your genes first. This will acquaint you with the virtues (and perils!) of enrichment analysis, and set the stage for a subsequent pathway analysis. The BioC package "topGO" is a good place to start: http://www.bioconductor.org/packages/2.12/bioc/html/topGO.html - Paul On Sep 5, 2013, at 7:59 AM, kaushal Raj Chaudhary [guest] wrote: > > Hi Bioconductor users, > > I am fairly new to bioconductor.
