Hi,
I am trying to pull down information from Ensembl using biomaRt and I
can't get the relevant biotype information (for Human). The old
'biotype' attribute doesn't exist, so what I see is 'gene_biotype' and
'structure_biotype'. I have no idea what the difference is, but I
can't
get either one. The error says it's probably an internal error to be
reported, but I also get this when I try to bring down what I think
are
incompatible attributes.
Thanks,
Elizabeth
