I see. I don't think we generate that by default. If you have a bunch of subjects I guess you could great a single vertex label at the frontal pole and another at occipital pole on fsaverage, then map each of them to each subjects and compute the distance between them. That will be a rough estimate. Or you could transform the brainmask.mgz to tal coords and see what the first and last a/p coords are. Neither will be perfect

I would like to use anterior to posterior length as a covariate in my DTI analysis. Is there an easy way to obtain this information for each subject? Thank you, Heather
