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
