Inherits RestraintBase.

## Detailed Description

Setup cross-link distance restraints from mass spectrometry data.

The noise in the data and the structural uncertainty of cross-linked amino-acids is inferred using Bayes theory of probability

Note
This class is only available in Python.

## Constructor & Destructor Documentation

 def IMP.pmi.restraints.crosslinking.CrossLinkingMassSpectrometryRestraint.__init__ ( self, root_hier, database = None, length = 10.0, resolution = None, slope = 0.02, label = None, filelabel = 'None', attributes_for_label = None, linker = None, weight = 1.0 )

Constructor.

Parameters
 root_hier The canonical hierarchy containing all the states database The IMP.pmi.io.crosslink.CrossLinkDataBase object that contains the cross-link dataset length maximal cross-linker length (including the residue sidechains) resolution what representation resolution should the cross-link restraint be applied to. slope The slope of a distance-linear scoring function that funnels the score when the particles are too far away. Suggested value 0.02. label the extra text to label the restraint so that it is searchable in the output filelabel automatically generated file containing missing/included/excluded cross-links will be labeled using this text attributes_for_label weight Weight of restraint linker description of the chemistry of the linker itself, as an ihm.ChemDescriptor object (see https://python-ihm.readthedocs.io/en/latest/main.html#ihm.ChemDescriptor). Common cross-linkers can be found in the ihm.cross_linkers module.
