p.s. how are you visualizing it? This works fine for me:

mri_convert -rl rawavg.mgz brainmask.mgz  brainmask_xformed.mgz
tkmedit -f rawavg.mgz  -aux   brainmask_xformed.mgz

then use alt-c to switch back and forth

Hi Bruce,

(aim: transform fs format back to original file
format)
when I run the commands you suggested:
mri_convert -rl orig/001.mgz brainmask.mgz
brainmask_transformed.mgz
the backtransformed image is in the original
coordinate boundaries, but it is not a the same
position as the original data (see attached example).

if your orig volume is in orig/001.mgz, then you can
do:

mri_convert -rl orig/001.mgz brainmask.mgz
brainmask_transformed.mgz

cheers,
Bruce
