Hi Mark,
Thanks a lot for replying!
Yes, I have tried this before. It gave the same results as
fslswapdim brain.nii.gz RL PA IS reorient.nii.gz
That is, same RAS coordinates still give close but different intensity values in FSL and exactly the same intensity values in FreeSurfer.
I think this could be probably because FSL rounds the RAS coordinates in a different way from FreeSurfer.
Best regards,
Xiuming
