Hi Peter
thanks for the info. Feel free to post this on one of the *many* blogs
howling for our blood :) I think that the effects in the paper reflect
default floating point settings in gcc on 32-bit vs. 64-bit, although we
haven't really investigated as it doesn't seem like a wise use of limited
resources (since no one would ever do a study that way in any case).

We run things on an Xgrid cluster that is now a mixture of Macs running Snow
Leopard (10.6.8) and Lion (10.7.x). We found the results given from
asegstats2table and aparcstats2table are identical after running 100
subjects on both Mac OS X 10.7.4 and 10.6.8 with Freesurfer 5.1. I also ran
a few subjects on the cluster and on individual computers (not on the
cluster so to speak) and the results are identical.
Best,
