[Bioc-devel] BiomartGeneRegionTrack question

This is a problem with the biomaRt package and its connection to the Ensembl archives, not Gviz. Here?s the call the fails:
listMarts(host="feb2012.archive.ensembl.org", path="/biomart/martservice")

It looks like Ensembl is no longer providing a download for the feb2012 archive. You could try the May2012 one, which according to this table (http://www.ensembl.org/info/website/archives/assembly.html) should still provide the mm9 (NCBIm37) genome:

bm <- useMart(host = "may2012.archive.ensembl.org",  biomart = "ENSEMBL_MART_ENSEMBL", dataset = "mmusculus_gene_ensembl")
bmTrack <- BiomartGeneRegionTrack(start=26682683, end=26711643, chromosome=7, genome="mm9",  biomart = bm)

I?ll update the automated mapping from UCSC genome identifier to Biomart within Gviz, however I am more and more convinced that this whole setup is not ideal. I simply do not have the time to keep track of all the Ensembl changes and new genome versions. There really should be an annotation package or the like maintained by Bioconductor core or within the biomaRt package that gives a mapping from a UCSC genome identifier to  an Ensembl genome version and the Ensembl archive to access that.
