Hi Fs Experts,

In order to calculate the mean diffusivity MD in my DTI data I did the following:

1. For the Eigvals.nii (the output of dt_recon) I used the following command line: fslmaths eigvals –div 3 md.nii

2. mri_vol2vol –mov md.nii  --reg register.dat  --fstarg  -- interp nearest -- o md.anat.mgh

3. mri_segstats --seg $SUBJECTS_DIR/mri/aseg.mgz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --seg-erode 2  --i md.anat.mgh --sum md.stats

is this correct ?

I highly appreciate any suggestions and advices

Mohamad
