Thanks Doug, the problem is that I have a volume overlay. When I register avg305T1.nii with Colin27 I have a different register matrix than when using single_subject_T1.nii.
Do you think that this procedure will work (scripted for every subject)? - *bbregister --s Colin27 --mov S_01 --init-spm --reg bb_Colin27_S_01.dat --t1* * * *and then* * * *- **mri_vol2vol --mov myROI.mgh --reg bb_Colin27_S_00.dat --fstarg --interp nearest --o S_01.myROI.bb.mgh* * * thanks again!
