The labels below have been histologically validated on exvivo samples.

= Using the labels on your data =
=== For internal users ===
The dev version of freesurfer has a -balabels flag for recon-all which creates perirhinal cortex labels on your subject and Brodmann Area labels as well.
=== For external users ===
To map these labels onto your own data you will use the fsaverage subject as well as the [[mri_label2label]] command
The section below gives the details of commands to load the label file in text editor, tkmedit, and tksurfer
{{{
cd $SUBJECTS_DIRcd
mri_label2label \
  --srcsubject fsaverage \
  --srclabel rh.perirhinal.label \
  --trgsubject subjid \
  --trglabel subjid/label/rh.perirhinal.label \
  --hemi rh \
  --regmethod surface
}}}
To take a look at the newly created label on your subject:
{{{
less subjid/label/rh.perirhinal.label
}}}
To load the label in tkmedit, first load the subject you want to work on:
{{{
tkmedit subjid orig.mgz
}}}
Then on the menu bar the top of tkmedit tools window, go to '''File --> Label --> Load Label --> Browse --> rh.perirhinal.label''' and hit 'OK' on both windows.  The label will be visible now.
The label can be edited when the Select Voxels button is chosen.  Use the middle mouse button to add to the label.  Use the right mouse button to delete from the label.  If this was your own subject: make sure you save your edits by going to '''File --> Label --> Save Label'''
To load the label in tksurfer, first load the subject:
{{{
tksurfer subjid rh inflated
}}}
On the menu bar at the top of tksurfer tools window, go to '''File --> Label --> Load Label --> Browse --> rh.perirhinal.label'''
Information on how to edit labels in tksurfer can be found at [[tksurfer_labeledit]]

To make the average probabilistic maps, Bruce used mris_spherical_average
