Hi Freesurfers,
we have FreeSurfer running on 10 computers:
7 computers with suse 10 32bit, freesurfer 4.5.0 32bit 3 computers with debian 5 64bit, freesurfer 4.5.0 64bit
recon-all -all -i finished on all of them without any errors, so i assumed the best. out of curiousity i processed one of the subjects on both systems, and checking the results in tkmedit and tksurfer i noticed that they are visibly different. (thus in this case one of the surfaces does not look quite ok, other subjects processed on that system look fine however, i haven't looked through all of them yet). screenshots attached. also, i just started recon-all -all -s bert on both systems, so i can compare them to the original bert.
what could be the reason for this failure at reproducibility?
