I began working with panTro3 assembly of the UCSC. This assembly corresponds to CGSC Build 2.1.3. See here: https://genome.ucsc.edu/FAQ/FAQreleases.html
Now, I have to cross annotations with ENSEMBL (Indeed, I need to use Biomart tool: http://www.ensembl.org/biomart/martview/2e4aac505f5cf5e0ac255b4a215a056c). But It seems that between Release 64 and 65 they passed directly from Chimp 2.1 to Chimp 2.1.4. I researched some information and found that Chimp 2.1.3 renamed as a Pre! See here: http://pre.ensembl.org/Pan_troglodytes/Info/Index and here http://www.ensembl.info/blog/2011/06/10/new-pre-site-for-chimpanzee/
Is it a way to solve this problem? How may I use Chimp 2.1.3 assembly in Biomart with GrCh37 as reference genome (I was using an archived versions of the Ensembl: http://grch37.ensembl.org/biomart/martview/cbe191dccbe8e5a314cfebeaa8862ca0), but seems not possible to cross between different releases of the ENSEMBL.
