I use SUPCOMB from the ATSAS package to fit the Xtal structure to the SAXS model. Then open this fitted file and your SAXS model again in pymol and you’ll see the fit.

Subject: [ccp4bb] How to fit BioSAXS shape to the Structure

Dear all,
I am new to saxs and I get the model by saxs data and I have a structure. I want to fit the structure to the shape but I can just open them in PyMol.
Can any one teach me to fit them?
Best,
Weifei
