HI Markus,
that's one of Christophe's labels, so would only be in the aparc.a2005s+aseg.mgz. Have you cheched the aparc.a2005s.annot on the surface to verify that it is present there? There are also some labels that don't appear on every subject, Christophe would know if this is one of them.
cheers, Bruce

Dear all,
I used mri_extract_label recently to get NIfTI -binary maps for certain anatomical landmarks, e.g. the Gyrus temporalis inferior of the left hemisphere (cortex) which index is listed in FreeSurferColotLUT.txt:
mri_extract_label $FREESURFER_HOME/subjects/VP1/mri/aparc+aseg.mgz 1009 $FREESURFER_HOME/subjects/ROI/VP1/CL_IT.nii.gz
This works fine. Now I want to extract the labels of anatomical landmarks like
4181 wm-rh-S_temporal_transverse
I tried every segmentation file I found (aparc+aseg.mgz, wmparc.mgz, aparc.a2005s+aseg.mgz), but only ended up with empty maps. Where I can find or how can I create the necessary segmentation volume?
Regards,
Markus
