Hi,

I am trying to run mri_cvs_register between a subject and another set of 10 healthy subjects (all analyzed with FS-5.0.0), but in all cases it fails on:

trying to execute elastic registration -> cmd line = surf2vol -fixed_mri .........

error executing surf2vol at /opt/freesurfer/bin/elastic_registration_CVS.pl line 162

My commandline is

mri_cvs_register --mov S1 --template S2 --outdir $SUBJECTS_DIR/CVS --nocleanup

Thanks for suggestions,

Martin
