GSEA single cell

Hello, I am analyzing single cell data. I ran Seurat's FindMarkers function to find the differentially expressed genes between each diseased and healthy celltype. I wanted to do Gene set enrichment analysis using clusterProfiler package. How to rank genes before using it.

gsea scrna-seq

Hi. I am looking for paper or justification about using :

sign(log2Fold )* -log10(pvalue)

Do you have any ? Thanks

Hi,

If you are interested in the magnitude of change, you can use the log2 fold-change values for ranking.
