I am new to DTI analysis and I am trying to follow up the manual. I have 2 questions: 

1) I cannot find any data related to CVS space in the $FREESURFER_HOME/subjects

Can you please help me find or get  the "cvs_avg35/mri/norm.mgz"? Currently, I am using FreeSurfure 5.1 on Linux, is CVS space available for the latest version?

2) How should I change these commands to use MNI space instead of CVS? 

mri_vol2vol --targ $FREESURFER_HOME/subjects/cvs_avg35/mri/norm.mgz \

            --m3z $SUBJECTS_DIR/$subj/cvs/combined_tocvs_avg35_elreg_afteraseg-norm.m3z \

            --noDefM3zPath --reg $SUBJECTS_DIR/$subj/dtrecon/register.dat \

            --mov $SUBJECTS_DIR/$subj/dtrecon/fa-masked.mgz \

            --o $SUBJECTS_DIR/$subj/dtrecon/fa-masked.ANAT+CVS-to-avg35.mgz \

            --interp trilin --no-save-reg

Thank you for your help.
