Hi!

I ran mri_segstats as instructed in the wiki to extract ADC values from adc.nii. And as you can see below in my output, I think the decimal digits are truncated and missing the following decimal values. Is there an option or other way to get around this problem and extract ADC values from the ROIS with greater precision? Thank you!

    --seg $SUBJECTS_DIR/$subj/mri/wmparc2diff.mgz \
    --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt \
    --id 251 --id 3021 --id 3024 --id 3030 --id 12 --id 4 \
    --i adc.nii --sum adc.stat
