Not directly. You can create a mask using mri_binarize of the range you want, then pass that as a mask to mri_segstats.

Thanks Nick,
I was able to extract T2 values! However, I noticed that mri_segstats appears to only sample T2 values from 0 to 300. Would it be possible to specify some other range for the stats output, say 20 to 90? I have attached a T2_MAP.mgz and T2 stats output.
Thanks again,
Carl

mri_segstats, for example: mri_segstats --seg aseg.mgz \ --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt \ --i T1.mgz \ --sum T1.stats produces a text file 'T1.stats' which has stats on each aseg struct as taken from the vol T1.mgz. n.
