[Freesurfer] extracting hand drawn ROIs to Afni space

Hi there,

Through the help of the Freesurfer Q&A staff I've been able to get ROIs drawn in tksurfer into an augmented aparc+aseg file of an averaged subject. I need to be able to get those ROIs, which are not part of the color LUT, into Afni space.

For ROIs that are already in the LUT, getting them to Afni is no problem, I simply use a 3dcalc command. However, I have the problem of needing to export newly parcellated and segmented ROIs that aren't in the Freesurfer LUT to Afni space.

Is there a way to do this short of creating a new "spot" for them in our LUT? If not, how does one go about adding ROIs to the LUT and/or creating a LUT specific to my needs (since the Wiki suggests not fussing with the original LUT)?

Thanks, Paul --
