not necessarily. That is a very small structure, and getting a few edge voxels wrong will mess things up a lot. Can you load lh-new-erc.mgz in tkmedit and load the surfaces too and see how good it did? doug

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 inlh.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 orat-leastbe close; I am guessing I am using mri_label2vol incorrectly ?
Could someone help me with this issue ?
Thanks
Mehul
