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
