> a. You said that we "could try segmenting the data and aligning the rc1 and rc2 from the fMRI". If I unerstood the Dartel correctly, the rc1 and rc2 are files that we get from the anatomical images? So shouldn't we align the rc1 and rc2 with the fMRI? Or is there a procedure to get these files from the fMRI data?
If you use New Segment on an fMRI scan (which may or may not work
well), then you can get rc1 and rc2 files.
> b. If we don't do a VBM study, is it right that we shouldn't normalize the anatomical images?
If you don't need them for anything, there's no point in generating
them. Usually, when SPM uses a file for any purpose, it asks you to
select the file.
