Hello. I am analysing RNA-Seq data for 8 samples (2 treatments, 4 repetition each). I just finished the gene count using featureCount (Subread). How do I generate a matrix to use on DeSeq2 from the files (.RDS) genereted from featureCount? Do I just create a file with the gene_id and the counts? Also, what do I have to put (what are the columns) in the Metadata file? Thanks in advance.
