I would need to go for some archaeological expedition to figure out exactly why, cannot do ATM. FWIW -- anyways - this is just a demo dataset. If you really want to get/analyze haxby2001 -- it is available from openfmri/openneuro in full "original" shape as ds000105 If you have datalad, you can datalad install ///openfmri/ds000105 and then cd ds000105 git checkout 1.0.0 to get old "openfmri" (not BIDS) layout for the dataset. Unfortunately we didn't come up with a convenience layer for BIDS datasets yet within PyMVPA. -- Yaroslav O.
