I've tried running auto-recon with version 5.3.0 (on Mac OSX v10.8.2) and the processing stream seems to fail at the intensity correction point. Not sure if it helps, but when I look at the output from the PBS script, I see "nu_correct: Command not found." 

Any suggestions on what I might be able to do to fix this? Any help would be greatly appreciated.
