Affymetrix data in BioMart/Ensembl search

Affymetrix probeset annotations have recently been patched in the core database. The updated information will be visible in all the main Ensembl web pages, including ContigView and TransView. However, it has not been possible to update the mart databases or Ensembl search indexes, which may return some spurious results.
