I have some predicted RefSeqs, such as XM_005261067 or XM_005255527 and would like to retrieve the hgnc_symbol using BiomaRt like this:
refseqids_XM = c("XM_005261067","XM_005255527") gene_XM <- getBM(attributes=c("refseq_mrna_predicted","hgnc_symbol"), filters="refseq_mrna_predicted", values=refseqids_XM, mart=ensembl) gene_XM
However, this gives me no result:
 refseq_mrna_predicted refseq_mrna <0 Zeilen> (oder row.names mit Länge 0)
I am not sure, but maybe these XM RefSeqs are too old and were removed from the dataset? Unfortunately, this is what I have to work with, as this is returned from our analysis pipline. Any idea on how I could still retrieve information using these XM RefSeqs would be highly appreciated.
Thank you very much, this helps a lot!
