I have a quick question regarding the launch of tksurfer. I have recently downloaded Freesurfer onto a Mac OSX after having some experience with it on a previous Mac. However, it had been preinstalled on that Mac, and I am afraid that I have perhaps installed it wrong on this one as when I test the launching of qdec and tksurfer, nothing happens. The terminal doesn`t spit out a command error, but it never launches the program. This was also a problem on the previous Mac for qdec but not for tksurfer. Therefore, I have tried to install everything again from square one and am not sure why now neither program is launching. I am simply trying to test the command "tksurfer bert lh pial". My environment is setup with Freesurfer and I am trying to launch from the surfs directory, as that worked on the previous Mac, but it is still giving me nothing. Any tips you could provide me with?
