[Chimera-users] FoxS in Chimera for SAXS curve fitting

I was wondering what version of FoxS the current release of Chimera employs for goodness-of-fit calculations to small-angle X-ray scattering curves using crystal structure models? Also, if any specific parameters are used other than what is default? I obtain quite different values using standalone FoxS binary or using the online server versus what is output by Chimera. Thanks, Eugene
