#include <IMP/saxs/ProfileFitter.h>
Inheritance diagram for IMP::saxs::ProfileFitter< ScoringFunctionT >:ProfileFitter is a class for fitting the two profiles with user-defined scoring function that is a template parameter. By default chi score is used. The scoring function template parameter class has to implement three basic functions: compute_score, compute_scale_factor and compute_offset. see ChiScore for example. Currently three scoring functions are implemented: ChiScore, ChiScoreLog and ChiFreeScore.

| Float IMP::saxs::ProfileFitter< ScoringFunctionT >::compute_offset | ( | const Profile * | model_profile | ) | const |
computes offset for fitting for fitting the modeled profile
resampling of the modeled profile is required prior to calling to this function, in order to match the q values of the exp. profile. this is not done by default to minimize the number of calls to resample.
