[pymvpa] how to ignore subsets of data?

[Alexandra Woolgar]

Hello,

Apologies if this has been covered already, I couldn't see anything about it in the archives.

Is there a simple way to tell PyMVPA to ignore whole conditions? I have 12 conditions, all of which occur in each chunk, and I want to use only a subset of the conditions in the classification analysis. Since I'm planning to run several analyses each using a different subset of the conditions, I was hoping I could tell the toolbox to ignore some of the conditions (perhaps by changing the labels, for example?), rather than having to create new 4D files each time?

Thanks very much,
Alex
