Hi Douglas,
Does LIA means the stored intensity changes first from left to right, followed by changing from inferior to superior, and the slowest changing is from posterior to anterior?
Best Regards, Yi

Run mri_info and see the Orientation string. Eg, LIA

Dear Freesurfer experts,
I used the following mri_convert command to extract the skull stripped image and save it to a txt file. The file contains only one column, and has 256*256*256=16,777,216 rows. Does anybody know the ordering in which 256*256*256 array is transformed to the vector (eg, which of R-L, A-P, S-I changes fastest and slowest). Thanks!
mri_convert $datadir/$subj/mri/brainmask.mgz $target/$subj.txt --ascii
