[edit] Fetching sequences
I found this thread very informative. --Jhannah 08:45, 25 January 2008 (CST)
I don't think there's a direct BioPerl interface to Ensembl, but BioMart at Ensembl itself will get you sequences (and lots of other things if you want) given a list of Ensembl IDs. http://www.ensembl.org/biomart/martview If you want to be able to get Ensembl sequences from a program, there's the Ensembl API: http://www.ensembl.org/info/using/api/core/core_tutorial.html
Various approaches are discussed here: http://www.bioperl.org/wiki/Getting_Genomic_Sequences Since you have ENSEMBL ids I'd think that would be the way to go.
