Dear Freesurfer Folks,
I have returned to the problem of trying to extract T2 values from a T2-map using aseg & mri_segstats.
When I attempt mri_segstats it only returns a small subset of the regions from aseg (see attached file).
I would like to attach the T2 map but the file exceeds the 25mb limit for gmail (could I drop the file somewhere?)
Could the T2 values need to be in a special format?
Thanks very much for your help.
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.
