Dear FSL wizards, I am just going through some of the fsl course material again, and noted the alt gui calls required for mac. Just curious, why not add a something like this to the respective scripts (e.g., beginning of "feat"), so that it's the same cross-platform? #\ [[ $(uname) == "Darwin" ]] && [[ $(echo "$(basename $0)"|cut -c1) =~ [A-Z] ]] && ("$(basename $0)"_gui &) && exit 0 Cheers, Aaron
