I am mapping my data to mmGRCm38 v92. However, when I use
tximport and biomart to annotate my transcripts to gene IDs I think that it annotates using the most recent ensembl version for mouse. Is that a problem?
I use the following code:
mart <- biomaRt::useMart("ensembl", "mmusculus_gene_ensembl", host = "uswest.ensembl.org")
Should I be using the code below to make sure that I am using the same version?
mart <- biomaRt::useMart("ensembl", host="http://apr2018.archive.ensembl.org", "mmusculus_gene_ensembl")
