Dear pyMVPA group, So I succeeded finally with the Searchlight.
Now I have some questions regarding RSA: - As I can see here: http://www.pymvpa.org/examples/rsa_fmri.html in the first step 'ROI pattern correlation distances' are computed and plotted. I would like to have something similar, where I get for starters just a (dis-)similarity analysis with no searchlight involved, however I would like to get for instance for my binary problem just a 2 x 2 RSA matrix, i.e. not for each voxel as is now the case, but a whole brain result comparing the two conditions. How would that be conventionally done? - Also, is there an alternative to z-scoring to rest when I have not modelled rest explicitly (just z-scoring with mean and stddev of both conditions?)? Many thanks, Pegah
