Hello AFNI team,
I have a simple (but crucial) question concerning 3drefit,
I received a dataset with incorrect header information (in particular L and R are FOR SURE reversed but not only).
Using 3dinfo the original orientation was LPI,
Using the command
3drefit -orient LSP -deoblique
I have now an image in the correct orientation for SI and PA, however, I still don't know if L and R are correct.
To do so, I checked if the right was still on right by modifying the right hemisphere (I added a sphere of "1") and then I applied the previous command
It appears that after this transformation the right sphere is on left (despite I didn't put RSP), which probably makes sense since I guessed, that inverting S and I has changed LR,
so my belief is that L and R are correctly oriented with
3drefit -orient LSP -deoblique
Am I right?
