Dear Matt, Bruce, I verified the scipy version: 0.9.0. The installed numpy version is 1.6.1. What versions are required? Thanks a lot!

Can you verify what scipy version you have? That is, I do see that the return value for this call did change sometime in the past 2 years, though I'm not sure exactly which version. I'll try to commit a patch to allow this older version to github today. But, I suspect that older scipy versions might cause other problems. I should probably put in a more exact check for required scipy version. --Matt _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit
