Hi there!I'm getting the following message when I try to fit my data:WARNING. The following variables had no effect on the fit: !! >> amp !! >> enot !! >> delr !! >> ss The data that I am trying to fit is the Cu metal example that come with the iffefit package. I am running Artemis on a Mac, OSX 10.4.11.I could run the fitting on a mac OSX 10.5 and it worked fine. I reinstall the IXAFS package but it didn't work.I am wondering what could be wrong with my machine/software?Thanks a lot.Juraci Sampaio _________________________________________________________________ Confira vídeos com notícias do NY Times, gols direto do Lance, videocassetadas e muito mais no MSN Video! http://video.msn.com/?mkt=pt-br
