 You can check the post (quoted below) to verify the setup for the 7.4..1 release.   Instead of running the freeview command as listed in the post, you can run the mri_info command with no arguments to get the help info about the command line options.  If mri_diff runs and prints out the help output, then the issue is likely your command line arguments. - R.. bash-3.2$ mri_info USAGE: mri_info fname1 <fname2> <options>
