Hi all,
I just wanted to follow-up on this message with one extra piece of information added:
The two brains are exactly identical. Considering that we have two identical reconstructed brains (exactly the same as each other), with the only difference being that one of them is a little bit shifted and rotated in comparison to the other one, if there a way to measure the amount of this rotation and shift? If yes, can this information be used to counteract this rotation and shift? In other words, can we rotate and shift the second brain back in the exact opposite direction, so it completely overlays the first brain using freesurfer?
Thank you and all the best, Ela ________________________________ From: Salar Dini, Elaheh Sent: Monday, January 31, 2022 6:46 PM To: Freesurfer support list freesurfer@nmr.mgh.harvard.edu Subject: Recon-all reconstructed image coordinates
Dear Freesurfer developers, In the link below, you see two brains belonging to the same subject:

while one of them is reconstructed with FS7.2, the other one is reconstructed with a pipeline that uses another code for extracting brain tissue (BET Mask) and then use FS6 for the remaining stages of the reconstruction.
While the final result of both constructions matches in most aspects, they don't occupy the same coordinates in space. Is there a way that we can match the coordinates of each voxel for two images? Or in other words make them compatible.
The Platform we use is CentOS7 .
Thanks and all the best, Ela
