Hi all, I am new to RNAseq analysis and am using GSEA to start with. I have watched Katherine West's tutorial video which was very helpful, but I am trying to figure out which chip platform I need to select as the data I received back from the genomic research facility uses different IDs than the ensemble IDs in Katherine's sample data set. I have listed a sample of the IDs below. The data is from microglia isolated from mouse retina. Thank you very much!
