Hi there,
I'm using Ensembl biomart to extract information about Affymetrix mouse
exon arrays. I have a set of Affy probe IDs and I want to map them onto
Ensembl exon IDs. I can put a set of IDs into the filters and get out
exon and genes ID attributes, from the "Structures" attribute list.
However, I need a mapping, so I also need the Affy IDs themselves. Since
the Affy IDs are only available from the "Features" attribute list, I
can't have both in the same output.
Is there a way to tell biomart to preserve the filters in the output, so
I can tell which Affy ID maps to which Ensembl exon ID?
This issue seems similar to one listed here:

Thanks,
