Hi Harpreet,
Thanks for reporting this. getSequence is a wrapper function that makes
thing easy to retrieve but it expect certain things such as that the used
filter is also an attribute that is retrievable. In this case
refseq_dna_predicted is given as filter but the corresponding attribute is
refseq_DNA_predicted so these are not the same and this makes your query
fail. I'll investigate this mismatch and try to fix it. In the meantime
you could do your query:
getBM(c("ensembl_gene_id","3utr"), filters= "refseq_dna_predicted", values
= "XM_940223", mart = ensembl)
This should work.
Cheers,
Steffen
