Yes. Using affine vs. nonlinear registration to the atlas shouldn't be as big a deal for tracula as, say, for a voxel-based analysis. That's because the anatomical priors used by tracula don't use the exact spatial location of the tracts but the IDs of the anatomical labels neighboring the tracts.

Hi Anastasia,

Ahh.. I used the regular 5.1 and pointed to our dev folder where the cvs_avg35 (and cvs_avg_inMNI152) live. So, do you recommend skipping cvs registration for now?

Thanks in advance! Verena

Hi Verena - Which version of freesurfer are you using? In the public release of 5.1 the CVS registration option in trac-all is disabled.

Dear Tracula Team,

I have been running into problems during Inter-subject registration at the mri_cvs_register step: it aborts with Image Exception : #22 :: ERROR: Could not open image /gablab/p/BGFU/data/freesurfer/cvs_avg35/mri//norm.mgz. But norm.mgz exists at the specified location and it can be opened with freeview without problems.

Did I oversee anything? Thanks in advance! Verena
