Dear Dr. Ravel,

I want to ask you that when I use the new version "Artemis 0.9.26" I have two problems. (1) The fitting Range was reported to be a error that the Rmin should be larger than the Rkbg value. It makes that the fitting range cannot be smaller than 0.9 (the Rkbg value is 0.9). (2) When Fitting the Debye?CWaller factor  (ss) and coordination number (N), although I use "abs()" to make it to be positive, but the fitting results still be negative. But I did not meet these problems in the old version in Artemis 0.8.012. I am wondering that whether could you tell me how to solve these problems. Thank you so much.

Sincerely,

Huan
