[pymvpa] Combine the fMRI data with other data in the pattern analysis?

[Nynke van der Laan]

Hello,
I have a question concerning searchlight analyses: Is there a build in
possibility in pyMVPA to add an extra variable to the pattern
analysis? E.g., if you have for each sample, next to the neuroimaging
data also skin conductance measures (1 per sample/scan). Would it be
possible to add this variable as a covariate to be able to see whether
this variable can improve the prediction accuracy? So when you run an
analysis with only the functional scans, and one with both the skin
conductance and the functional scans, you can see whether that adds
any information.
Thanks in advance for answering my question!
Best regards,
Nynke
