[Freesurfer] mri_extract_label 4181

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
