RE: Transform individual ROIs to MNI space
I got it to work by using FSL's fslcpgeom to copy the header
information from the translated T1 scan to the tissue maps (since
they were created in the same space and geometry). Then after
structural normalisation on the T1, apply the same transformation
to the tissue maps using SPM. CONN/SPM and Freesurfer's freeview
show the tissue maps and T1 are transformed to MNI and are nicely
aligned again. FSL's fslview show a mismatch where the tissue maps
are still offset by some translation factor, but we're good to go
with CONN/SPM.
I'd still love to know if there is any easy way to copy the header information from the translated T1 to the tissue maps using functions from Matlab, CONN or SPM, so we can put everything in a single batch script.

Hi Alfonso,
Thanks for the quick response. We tried option 2, but we do have the problem that we require the 'set origin to (0,0,0)' option during preprocessing, otherwise SPM complains about to little overlap between scans during structural normalisation. How is this 'set origin' step performed? Is there a way to get the translation parameters? Because if we can apply it to the structural scan and then the same translation to our tissue maps prior to using CONN it should work with option 2.
Regards,
Jalmar
