#include <IMP/isd/CysteineCrossLinkRestraint.h>
Inheritance diagram for IMP::isd::CysteineCrossLinkRestraint:A restraint for cysteine cross-linking data. It models the frequency fexp derived from gel separation of cross-linked complexes. The experimental frequency fexp is derived as the fraction of dimeric versus monomeric complex, upon cysteine cross-linking. The forward model is derived from free energy calculations. The likelyhood is modeled as a normal distribution function truncated over the interval [0,1]. To contruct the restraint, the class CysteineCrossLinkData and CrossLinkData have to be initialized (see for instance test_CysteineCrossLinkRestraint.py). Input parameters and constructor. There are two different constructors p1 and p2 are the two cross-linked sites. \( \beta \) is the beta parameter in the distribution function. The \( \alpha \) parameter is constrained by the condition that the variance is gaussian by the formula \( \omega \) is a scale factor for the beta parameter, to allow for outlier detection. Usage: Construct the ambiguous set using CysteineCrossLinkRestraint( \( \beta \), \( \omega \), xlyield, \( f_{exp} \)) method. The model frequencies of each individual copy are summed, weighted and multiplied by the unknown crosslink yield (epsilon). Pass individual cross-linked pairs to add_contribution(p0, p1, w) command, where "w" is a state weight parameter.

kernel::Restraints should store the particles they are to act on, preferably in a Singleton or PairContainer as appropriate.
