I need to determine whether a gene is mitochondrial or not for C. Elegans automatically from its name by running a regular expression on a dozen of thousands of gene names. Currently I am having gene symbols like:
clec-190, clec-189, 21ur-8912, nduo-1, 21ur-6539, 21ur-13096, nduo-6, 21ur-14241, ndfl-4
I tried running
grepl("^mt-", symbols) and it found nothing. I am sure that there are some mitochondrial genes just from their descriptions. I would assume that first I need to convert gene symbols to some other symbols to do that but I am not sure here.
Basically, I am trying to do it in a similar way to the tutorial of single cell RNAseq.
