Yes, there will be some minor differences between centos4 and centos6 build. The differences are due to the different versions of gcc used for the different distributions. The centos6 build uses a newer version of gcc which has optimization options not available on the version gcc for the centos4 build, and that makes for run-time differences in recon-all.

Hi, I have two identical Red Hat 6 boxes, to run recon-all-s.

I just realized that in one of those I had freesurfer 5.3 for CentOS4 and in the other one I had freesurfer 5.3 for CentOS6.

I have one experiment were subjects used boxes indistinctly.

According to how the software is built, should I expect different results among them?

Many thanks for your help, Gari
