Hi:
Yes... The PET image that I want to corregister to freesurfer (SPMT_0001) is the result of a Two-sample t-test between a patient and a PET database... fot that reason, I have the image in MNI 152 space... I thought that I have two possible solutions:
i) use 12 DOF to corregister the SPMT_0001 image to freesurfer ones... ii) apply the inverse transformation (that I use to normalize the PET of the patient to MNI 152) to SPMT_0001, and then use 6 DOF to corregister SPMT_0001 to freesurfer...
Sincerely

yes, but I wouldn't use it for this. Here you really want to use the data before resampling for registration. You can always map that into the MNI space using the SPM transform

Is there some feature like the fast fluid registration in the dev pipeline?

p.s. make sure you are registering the original images, not the ones transformed into MNI space

Hi:
I have a freesurfer processed patient and the PET of the same patient processed with SPM... the PET images are corregistered to MNI152... How can I corregister the PET to the freesurfer images ?... I tried to corregister using bbregister, but I got bad results (I think that I need 12 DOF)...

it's 6 by default. Not sure if 12 is implemented yet, but I know Doug was thinking about it.
