Hi:
I am using Cuffdiff log2(fold_change) values in 'rnk' file for GSEA.
Althought I had 8K genes, my C2_all set enrichment was only 1 gene set at FDR-25%.
My question is - is log2(fold_change) values - suitable for GSEA enrichment.
I mean - can I compare the AFfy log2 fold changes and cuffdiff log2(fold_change) values and do Pre-ranked enrichment.
Is the distribution meaningful for GSEA enrichment.
thanks
Adrian.
