Hi list,
I am trying to visualize a .nii ROI coming from MEG, which is in Colin27 space. 

I can visualize it perfectly in mricron and tkmedit with the following command: 
tkmedit -f path/to/spm8/canonical/single_subj_T1.nii -overlay MEG_ROI.nii -fthresh 0.5
(single_subj_T1.nii is Colin27)

but when I visualize it with:

tkmedit Colin T1.mgz -overlay ./rC_vs_D_band1_0.01_left.nii -overlay-reg /home/glerma/glerma/GIT/bcblscripts/FREESURFER/ROI/Mikel_SingleSubject_to_Colin.dat -fthresh 0.5 -surface lh.white -aux-surface rh.white



The result is wrong, and different from the first tkmedit.


Should I convert the MEG_ROI.nii ni some specific way to make it work? Any suggestions?


Thanks,

Gari 


The registration matrix between single_subj_T1.nii and Colin27 is the following one:
