hello all, I want to study the co-expression analysis using RNA seq data by WGCNA analysis ( Organism- Homosapiens). I created the gene count matrix file (Package - Subread ) as the input file. For mapping the Ensemble ID into the gene symbol, I need a gene annotation file. Please share your knowledge, how to get the gene annotation file!
You can just use one of the GENCODE GTFs: https://www.gencodegenes.org/human/
I would use the 'Basic gene annotation CHR'.
Be sure that you are matching based on reference genome version, too. The page to which i linked, by default, as of today (April 9, 2020) is for GRCh38 / hg38.
