class	PoseFromSFRBuilder
	The PoseFromSFRBuilder is responsible for taking a partially-processed representation of a structure file, a structure-file repersentation or StructFileRep, and it constructs a Pose from it. Its primary output is a Pose, but it also keeps track of the "missing atoms:" the set of atoms in the Pose whose coordinates were not given in the original file. More...

core::Real core::io::pose_from_sfr::bonding_distance_threshold	(	std::string	element1,
		std::string	element2
	)

Get theshold distance below which two atoms are considered bonded. (1.2*covalent)

The closest distance of a non-bonded contact is likely to be something like the opposite atoms cyclobutane. This would be sqrt(2)*covalent bond distance. We thus set the contact distance threshold to 1.2*covalent bond distance to allow bond length flexibility. In initial tests this looks to give a clean decision.

Pass-by-value is deliberate, as we want to strip the elements of whitespace

void core::io::pose_from_sfr::randomize_missing_coords ( AtomInformation & ai )

randomize missing density

The missing density regions in the input pdb should have 0.000 in the placeholders this routine puts random coordinates wherever there is 0.000 for mainchain atoms. tex - that's a stupid way of defining missing density, as atoms can be at the origin for other reasons. This has been updated to check for occupancy to define missing density rather than atoms located at the origin.
