Hi Missy, yes, that sounds like at least part of your problem. What trouble did you have sourcing our env file? Can you send us the screen output? Bruce On Wed, 12 Sep 2012, Melissa Lancaster wrote: Hi again- I should have added that I am using Mountain Lion. I have downloaded Quartz and

flirt is found in the directory $FSL_DIR, where FSL_DIR is the var set when sourcing $FREESURFER_HOME/SetUpFreeSurfer.csh. What is the output displayed after sourcing SetUpFreeSurfer.csh? And what distribution are you using? What is the mri_convert command line being used? On Wed, 2006-03-15 at
