Hi, I think the "line endings from other operating systems" should be something that is handled automatically in the programs. That is, one should be able to run Feff8 on a unix system and use the results on a Windows or Mac machine without having to "clean" the files. Ifeffit is already insensitive to data files and script files from foreign systems, but for some reason I cannot justify, Ifeffit still fails to read feff.dat files from other foreign systems. I now have a fix for this (that works for me in one test case, and so needs some more testing!), so I'll release a 1.2.10 version with this fix soon (as soon as I have time to build and test a Windows dll). I'm sure it's easy for Artemis to automatically check and fix line ending problems for files.dat, etc. Sorry for the trouble, --Matt
