Verify atlases are in the same space #73

Closed disa-mhembere closed 9 years ago

disa-mhembere commented 9 years ago

Could you verify MNI152_T1_1mm_desikan_adjusted.nii and MNI152_T1_1mm_brain_incremented.nii are in the same space please?

Reason:

Graph built with MNI152_T1_1mm_desikan_adjusted != Downsample with atlas MNI152_T1_1mm_desikan_adjusted of graph created with MNI152_T1_1mm_brain_incremented.

Yep, they are in the same space (not sure if images can be displayed in issues but the attached image is them overlaid on one another. N.B. banding is artifact of the fact that incremented is 32 bit image in a 16 bit reader)

Ok -- moving debug efforts elsewhere. Thanks brosef

There is one voxel at (18, 119, 66) that is zero on the the incremented_atlas, but is non-zero within desikan. There are 92163 voxels incremented_atlas claims are in the brain, but desikan claims are outside (this is not great in theory, but ok for the purposes of downsampling).
