You can add --mul 1000 to multiply everything by 1000

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!
