Thanks Rotem
I would use step 3 for the wmparc instead of vol2vol.
you need both --seg and --seg-erode
--seg-erode 1 --seg /usr/local/freesurfer/ subjects/Anatomy0981/mri/wmparc2diff.mgz

Hi Doug,
Thanks you for directing me to my mistake in step 3 (see below new cmd line in step 3). What I did is the following -
- dt_recon --i

it created many *.bshort files
My qs:
- Should I repeat step 3 with the wmparc.mgz or is it not necessary ?
- How do I plot all MD values like I did before for FA values ?
trying to use -
mri_segstats --seg-erode 1 /usr/local/freesurfer/subjects/Anatomy0981/mri/wmparc2diff.mgz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --i /usr/local/freesurfer/subjects/Anatomy0981/DTI/fa-masked.mgz --sum /usr/local/freesurfer/subjects/Anatomy0981/stats/all_stats_MD-masked
always end with the same message - it wants a segmentation volume but nothing works ("unknown")... I used aseg.mgz for example and other options - nada. However, If I omit the "-erode 1" it reports the table, but for FA values. What do I need to change in step 3 and how can I fix the last step ?
Thank you for your help
