Hi, I've been trying to use biomaRt to access a previous release of Ensembl (63) but listMarts(archive=T) reveals only ensembl_mart versions 43-47. Has the support for archival versions of Ensembl been discontinued? I'm using R v. 3.0.1 and biomaRt 2.16.0.

Hi Greg, A better way to access an ensembl archive is to specify the archive URL in the host parameter like this: ensembl=useMart("ENSEMBL_MART_ENSEMBL",dataset="hsapiens_gene_ensembl" ,host=" jan2013.archive.ensembl.org") This will connect you to Ensembl 70 for example. To figure out which host URL to use for a specific archive version I usually go to www.ensembl.org, select my species of interest and then at the bottom of the page click on "view in archive site" then select the Ensembl version of the archive you want to use and see where the URL points to and use part of the URL before the first forward slash (e.g. jan2013.archive.ensembl.org) as host URL in your useMart call.
