Hi Ladan

that is a warning burried in the depths of some numerical optimization libraries we use that I don't think matters. Did you kill the recon job? I think it was running fine and you should let it go to completion then take a look at the results

I'm using freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0 and my operating system is 14.04.1-Ubuntu.

attached is the recon-all.log.
