Error with T1w/T2w maps

Hi,

When I created the T1w/T2w maps. I found an error and I had to replace the header of the registered T1w by the one of the T2w to create the map. I found that the issue was related to the *_T1w2anat-r.dof.gz and *_T1w2anat.mat transformation files. Assuming that both are the same (just converted from one format to another), when I apply the two files to the T1w, the resulting file using the _T1w2anat-r.dof.gz has a small difference in the header (around 110^-10), this difference is small enough to be ignored by FSL (I can overlay the maps correctly with fslview) but it's detected as a difference by the connectome workbench to create the T1w/T2w maps.

As I said, as a workaround just copying the header from the other image worked.

Best regards,

Manuel
