External Email - Use Caution
Thanks a lot! Running preproc-sess with the --per-session flag is exactly was I was looking for! Now that my functional runs are correctly registered to a reference image (so, to each other) I need to register them to a dataset of ROIs that were created outside freesurfer. These regions are in volume space and have the same resolution and box size of the functional runs. They are registered to the T1 that was used for the reconstruction of the surface. I've tried different functions for the registration but nothing really worked. I suppose I need a registration matrix that relates these regions to the reference image I used during the preprocessing and to apply this to each region. What's the best procedure?

Yes, if you run it with the --targ as orig.mgz for the given subject, then it will sample each run into the anatomical space (this can create enourmous data data files!). Alternatively, you can run preproc-sess with the --per-session flag and it will align all the runs to a single template but otherwise keep everything in the functional space

External Email - Use CautionI'll try to find some visual way to show what I mean, but it's really something mild and probably negligible. Do you know if is it possible with mri_vol2vol to give to all the runs that belong to the same subject the same system coordinates? So that each voxel across runs will have the same coordinates. I noticed that the transformation matrix is written in the header but it's not really applied to the data. Thank you!
