Hi,

I need to know how to access Ensembl bacteria via biomaRt, if it can be done.  

I can access all the non-vertebrate marts (fungi, plants, metazoa, protists) by their respective ensembl.org subdomains, but not bacteria.  When I try:

> listMarts(host="bacteria.ensembl.org")

I get this crazy result:

Entity 'hellip' not defined
Entity 'hellip' not defined
Entity 'nbsp' not defined
Entity 'raquo' not defined
Entity 'hellip' not defined

Again, for fungi, plants, metazoa, and protists, this approach works just fine.

Thanks,

Hi Ariel,

Since the expansion in early 2013 of Ensembl Bacteria from a few hundred to tens of thousands of bacteria, Ensembl Genomes has not provided a mart, as BioMart does not scale to this number of genomes. We're actively working on an alternative to provide access to all Ensembl and Ensembl Genomes data, and will be working with the BioConductor community to make sure this new service meets key requirements for data retrieval.

As for the odd response, I imagine that biomaRt is trying to access the old mart address and trying to parse the redirect page, so if there is a URL for the old bacteria mart in biomaRt, it needs to be removed.

Best regards,

Dan
