thanks a lot for your help! That really took us a big step further.
There're just two small questions remaining:
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?
b. If we don't do a VBM study, is it right that we shouldn't normalize the anatomical images?
Thanks again for your help,
