Dear All, Recently, I found the mouse gene annotation in biomart had been changed to the version GRCm38 (mm10). However, I want to use mm9 version. Could anyone give some suggestions about how to do this? My code is mart <- useMart(biomart="ensembl",dataset="mmusculus_gene_ensembl") Thanks! Best all! David! [[alternative HTML version deleted]]

Hi David, This should get you there: mart = useMart('ENSEMBL_MART_ENSEMBL',dataset='mmusculus_gene_ensembl', host="may2012.archive.ensembl.org") Cheers, Steffen On Wed, Aug 29, 2012 at 10:10 AM, lemon tree <lemon.wang218@gmail.com>wrote: > Dear All, > Recently, I found the mouse gene annotation in biomart had been changed > to the version GRCm38 (mm10).

Hi David, From ?useMart I see archive: Boolean to indicate if you want to access archived versions of BioMart databases. Note that this gives access to only a limited number of archived BioMarts and the most recent archives are often not available. A better alternative is to leave archive = FALSE and to specify the url of the archived BioMart you want to access see vignette for an example. and if I then look at the vignette I see that this is outlined clearly on pages 14-15.
