Constructor & Destructor Documentation

def IMP.pmi.restraints.saxs.SAXSRestraint.__init__ (   self,
  input_objects,
  saxs_datafile,
  weight = 1.0,
  ff_type = IMP.saxs.HEAVY_ATOMS,
  label = None 
)

Builds the restraint.

Parameters
input_objectsA list of hierarchies or PMI objects that the SAXS restraint will be applied to. This hierarchy MUST be atomic. You can pass a list of CA atom particles to evaluate at residue resolution
saxs_datafilethe SAXS .dat file.
weightRestraint score coefficient
ff_typethe form factor to use, of the following types:
  • IMP.saxs.HEAVY_ATOMS: use form factors with implicit hydrogens
  • IMP.saxs.ALL_ATOMS: use individual form factors for all atoms. Does not build missing hydrogens.
  • IMP.saxs.CA_ATOMS: use residue based form factors centered at CA atoms
labelLabel for the restraint in outputs
