Dear list, I'm attempting to use the biomaRt library to annotate a microarray data set, and get the following error message (refer below). This code (replacing 'ensembl_mart_37' with 'ensembl_mart_36') worked fine a week ago, so perhaps the latest ENSEMBL release (16/2/6) is causing biomaRt some trouble?

Hi Matt, This is due to an unexpected change in the Ensembl BioMart database and I have fixed that in the BioMart version available from the devel repository. Note however that we are trying to remove the dependency on RMySQL and currently are updating the biomaRt package to do queries over HTTP (will be the default) in addition to the use of MySQL. Some functions are not yet updated and might give some errors for the next few days. The functions you are trying to use should already work properly. best, Steffen > Dear list, > > I'm attempting to use the biomaRt library to annotate a microarray data > set, and get the following error message (refer below).
