No. I just checked, they are not identical. Although some of numbers are the
same, many are different.

Are the other results identical? Eg, lh.aparc.stats?

Dear Freeserfer developers,
I have run recon-all for a bunch of subjects on the same machine for several
times. When I use the "mris_anatomical_stats" to calculate the statistics
(specifically, I am interested in average cortical thickness), I found that
for the same subject I got different results, as shown below:
$ mris_anatomical_stats -b QEN001 lh
.
128449 86239 243375 2.588 0.876 0.123 0.026 1496 133.3
/xxx./subjects/QEN001/surf/lh.white
$
$ mris_anatomical_stats -b QEN001_old lh
.
128449 86241 229554 2.404 0.835 0.123 0.026 1496 133.3
/xxx./subjects/QEN001_old/surf/lh.white
The results shows that some of the stats numbers ( such as the number of
vertices) are the same, but the "average cortical thickness +- standard
deviation (mm)" are different, and they differ quite a lot.
I have tried several subjects; some of them get the all-the-same results,
some of them not.
I am sure the subjects and the corresponding images are the same. Are these
expected results?
Thanks!
Xiaojiang
