Dear FreeSurfer community,

I have applied mri_cvs_register to subjects' T1 scans using FreeSurfer 6.0 and mri_vol2vol to warp fractional anisotropy spatial maps warped to CVS space. A previous post talks about functionality of "morph + downsampling" in a single step coming in the future: https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg30724.html.

Is this functionality now incorporated in mri_vol2vol?

For example, are there additional flags where I can specify the voxel size of the output volume as being, say 4mm x 4mm x 4mm?

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

--m3z

$SUBJECTS_DIR/$sub/cvs/final_CVSmorph_tocvs_avg35.m3z \

--noDefM3zPath --reg $reg --mov $vol \

--o $vol_cvs \

--interp trilin --no-save-reg

As it is, the output volume in CVS space as the same voxel size as cvs_avg35 template (1mm x 1mm x 1mm).

Thank you.

Best,

Chintan
