[Freesurfer] creating an entorhinal cortex volume from ?h.entorhinal_exvivo.label

Hi Folks,

I am trying to create an entorhinal cortex volume from ?h.entorhinal_exvivo.label using mri_label2vol

I cd to the subject dir ($SUBJECTS_DIR/bert) and the command I use is:

*mri_label2vol --label label/lh.entorhinal_exvivo.label --temp mri/nu.mgz --identity --o mri/lh-new-erc.mgz *

I took the sum of the voxels in this new mask i created (lh-new-erc.mgz) and it is 215;

I looked at the volume provided in lh.entorhinal_exvivo.stats and it is 925; (from the log file I believe this is created using the command:

mris_anatomical_stats -mgz -f ../stats/lh.entorhinal_exvivo.stats -b -l ./lh.entorhinal_exvivo.label bert lh white)

I was expecting the numbers to match or at-least be close; I am guessing I am using mri_label2vol incorrectly ?

Could someone help me with this issue ?

Thanks

Mehul
