Chi-square values < 1

#1 Post by BC_Flügge » 2018.06.15 10:16

Hello,

I try to build ab initio models with DAMMIF/GASBOR and I am always getting Chi-squares values < 1 (usually, around 0.4 - 0.6) no matter what. In my opinion, the raw data looks really good, but I am just a SAXS beginner. I also agree with the generated models as I have a crystal structure to check. I already read that too low Chi-square values are a matter of over-fitting, but I used the data as autognom generated them without changing anything. I will enclose the raw data and images of the fitted curves. As I really want to use this data, I hope for your help. Thank you in advance.

Cheers!
