[pymvpa] Coordinates retrieved from Searchlight

[Pegah Kassraian Fard]

 Hi all,


I am saving the coordinates corresponding to classification accuracies as
follows:

        max_i = np.argmin(sl_map.samples[0])  # min
        coord = db12s.fa[sprefix_indices_key][max_i]

        np.save(dir + '/coords' + str_label_set,
db12s.fa[sprefix_indices_key])



Now looking at these coordinates, it strikes me that they all are positive
- which can't be for MNI coordinates describing the entire cortex (I am not
masking). How can this be? And if these are not MNI coordinates, how could
they be translated to such?

Thanks,
Pegah
