Howdy - I'm trying to walk someone through the early part of the PyMVPA tutorial. We installed the latest PyMVPA 2.31 via macports; (the last time I did it it was v.2.2.0) and the directory names seem to have changed, s.t. the real tutorial data is in
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/mvpa2/data/tutorial_data_25mm/data which I think is different from where it used to be? Anyway, the documentation here: http://www.pymvpa.org/tutorial_datasets.html describes mask_vt.nii.gz as containing 577 features, but from what I can tell it's only got a single active voxel. Check it out: ❯❯❯ for file in *.nii.gz; do echo "for $file ==> " $(3dBrickStat -positive -count $file) done for anat.nii.gz ==> 352 for bold.nii.gz ==> 871200 for bold_mean.nii.gz ==> 600 for mask_brain.nii.gz ==> 129 for mask_gray.nii.gz ==> 28 for mask_hoc.nii.gz ==> 45 for mask_vt.nii.gz ==> 1 for mask_white.nii.gz ==> 34 There's other data in the .../mvpa2/data/ directory, but the bold data is of different dimension, the mask is of different dimension and also a different name. Am I missing something obvious, or are the dox and the PyMVPA distribution out of sync now? S
