Hi,
I just wanted to verify what the Talaiarch coordinates reported in tkmedit actually are. Are they based on Matthew Brett's 10/8/98 non-linear transform from MNI305 space or are they actually MNI305 coordinates? See screenshot.
I would like to get coordinates of voxels within subcortical structures for some fMRI work and need MNI coordinates rather than "true" Talaiarch. I'm trying to minimize the number of transformations.
Thank you,

the Talairach coords reported in tkmedit are the 'Brett' corrected coordinates. the mni305 are also available, but off by default, if you select View->Information->MNI Coordinates.

Those are 305 coordinates transformed to "talaiarch" through Matthew Brett's transform. doug
