also be sure to add the flag --a2009s to the end of the mri_aparc2aseg
command shown below (i forgot to mention this the first time aroun).
this will fix the problem where you were not seeing the correct labels
(you should now see the Destrieux labels when viewing in tkmedit).
per the Segmentation
We don't usually use the Destrieux atlas for this as the wmparc was
oritinally intended to measure gyral white matter. However, you can
still run the commands, something like
cd $SUBJECTS_DIR/subject
mri_aparc2aseg --s subject --labelwm --hypo-as-wm --rip-unknown \
--volmask --annot aparc.a2009
I want to extract wm volumes using wmparc for parcellations contained in
Destrieux 2009 atlas but when I inspect my wmparc stats file, most of the
volumes that I am interested in are reported as zero. What should I do to
read these volumes?
Many thanks
Lena
