I have a list of Ensembl gene IDs from different organisms and I would like to retrieve their sequences. I had used Biomart before, but it requires to specify the organism before one can download the gene sequences of a specific gene ID. This would not be feasible because I do not know which organism each gene belongs to, unless I search the gene ID.
Is there any solution to this problem that does not require me to learn Perl? I know Python.
Thanks in advance
