[pymvpa] classification selection

Hello PyMVPA community,

I just start using PyMVPA for some fMRI data analysis, and I got a question about classification selection.

I firstly used LinearCSVMC as my initial classifier, but it ran very very slow (it kept running for more than 2 weeks).

I am not quite sure where did I go wrong.  I then used another classifier - kNN. It ran much faster than the LinearCSVMC.

I was wondering if there was any restriction or cautions on using kNN for fMRI data analysis?

Thanks very much!
