HI Stefano,

stefano% ~> /Applications/Ifeffit/bin/ifeffit -i tcsh: /Users/stefano: Permission denied.

But that's implying that you can't even run ifeffit due to permission problems. That makes it seem much more about your system than about Ifeffit.

stefano# ifeffit stefano# ifeffit> print $&install_dir

Hmm, that's weird. The banner message didn't print and the prompt is wrong (it should be "Ifeffit>"). Any ideas why that might be?

stefano# ifeffit> print $&install_dir su: Illegal variable name. stefano# print $&install_dir su: Illegal variable name.

Hmm, that's weird too. I'm not sure what wrote "su: Illegal variable name." I'm pretty sure that is not from the ifeffit program. --Matt
