[BioC] Problem using 'biol_process' filter in biomaRt

[J.J.P.Lebrec at lumc.nl]

Hi,

I am having trouble retrieving GO annotations data using the 'biol_process' filter in biomaRt. I used the below code several months ago and it worked fine. The filter is NOT FOUND although it is definitely part of the listed filters as shown below.

Thanks in advance for your help,

Jérémie

Checking attributes and filters ... ok

  Number of columns in the query result doesn't equal number of attributes in query.  This is probably an internal error, please report.
