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.

Dear Freesurfer,
I have co-registered a map of whole brain T2-relaxation time values to the corresponding aseg.mgz for this subject (see attached jpegs). Does a tool exist in freesurfer to enable regional sampling of T2 values from the T2-relaxation time map based on aseg?
Thanks for any thoughts.
Happy New Year.
