I would like to use GSVA for enrichment analysis. By default, GSVA uses c2BroadSets data. Instead of c2BroadSets, I wanted to use c7Broadsets which is immune specific enrichment data. How to proceed with this?? 

Note: There are few blogs which talks about creating c5data using the gmt file available in molecular signature database. But, I have no clue how to proceed with that. Please let  me know.

Any update on this, Sathya? I actually would like to do the exact same analysis with the C7Broadset.

thanks,

David

You have to first go to the MSigDB downloads page. Once you login, scroll down to the section labelled "c7: immunologic signatures gene sets" and download the appropriate .gmt file. Then import the data into R with a command similar to the following:

myC7 <- getGmt("c7.all.v5.1.entrez.gmt")

If you get an error, you might need to specify the other parameters of getGmt:

myC7 <- getGmt("c7.all.v5.1.entrez.gmt", geneIdType=EntrezIdentifier(), collectionType=BroadCollection(category="c7"), sep="\t")
