Hello Everyone, I have a question, is it possible to use the Log2FC for doing the GSVA? In the past I used to use the rlog values or the normalized read working with GSVA from the Broad Institute or other tools, but working with scRNA-seq I can't have it anymore

I appreciate the help

thank you

Why can't you use your RNA-seq counts?

Hi Jared, It's a single cell RNA-seq where I have an expression gene list from SEURAT of different clusters, I want to do a GSVA on this clusters but Seurat gives AvgLog2FC only

thanks

Why not just do it on individual cells and compare between clusters using whatever metric you want (average, median, etc)? I've been involved in the development of a new R package called escape that will be in the next Bioconductor release that has a number of functions to make running ssGSEA via GSVA on scRNA-seq quite easy. You may want to consider that if you want a plug and play solution with additional visualization and comparison functions.

Hi Jared, Thank you for your answer, definitely I ll take a look to escape :)
