Hi Matt,
I just tried this on a fairly fresh OS 10.4 machine (Ifeffit had been installed over a year ago, when it was a 10.3 machine, and I wiped /Library/Perl/5.8.1 and /Applications/Ifeffit, and cleared the /Library/Receipt for Ifeffit....).
I got the same behaviour as Stefano.
feewwwww!!!!!! I am so glad it wasn't me doing something totally silly :-)
It looks like everything did get installed this time, but that the resulting version of Ifeffit depends on Aquaterm.
OK
Downloading and installing Aquaterm from the disk-image package from sourceforge.net was simple (though it requires a privileged password) and made Athena and Artemis run fine.
So my immediate recommendation is to install Aquaterm from Sourceforge. http://sourceforge.net/projects/aquaterm/
Great! I downloaded and installed Aquaterm and imemdiately things are fine. Thanks a lot! Stefano PS: I hope you will have the time and patience to respond to the question of how IFEFFIT calculates Nidp, and by consequence how it converts chi^2 to reduced-chi^2... It's 10 pm here in Italy and I quit for the day. Have a nice day or night wherever you are.
