Hi:
I used gencode GRCm38 GTF for annoation during reads counts using RSubread.
I can't get the gene symbol following the DEseq2 manual:
resTC$symbol <- mapIds(org.Mm.eg.db, keys = row.names(resTC), column = "SYMBOL", keytype = "ENSEMBL", multiVals = "first")
I looked over it again and found that the geneID I got is in this format:
ENSMUSG00000029848.11
So I manually put it this geneID into NCBI gene and it does not match anything. However, if I use ENSMUSG00000029848 it will tell me it is "Stra8".
Can anyone tell me how to solve this problem?
Thank you very much,
I got an answer from a previous post by others (https://www.biostars.org/p/301116/#496172).
But when I tried to ger rid of trail numbers using:
it turns out everything was replaced with "".
