External Email - Use Caution
Can you send the recon-all files from two of your runs that give
different results? BTW, we do these kind of tests weekly and everything
always comes out identical

Dear FreeSurfer team,
We were interested in the reproducibility of multiple runs of
recon-all and repeated recon-all 1416 times on the same subject.
We then checked the left and right brain results for the volume
obtained from the Aseg process. The right brain showed exactly the
same volume, while the left brain showed a small variation.
We thought that the variation in volume between the left and right
brains would be the same. But why is this not the case in reality?
The volume_attemps1416.csv is attached. For example, the
Left-Lateral-Ventricle in this file has variation, but the
Right-Lateral-Ventricle has no variation, as shown below.
*Left-Lateral-Ventricle
*12377.8
12375.9
12375.9
12380
12376.4
...
*Right-Lateral-Ventricle
*7514.7
7514.7
7514.7
7514.7
7514.7
...
