Detailed Description

The used scoring function is a simple steric energy function with linear fallof that is capped for small distances to avoid explosion of energies. This is identical to the clash function used in SCWRL 3

Function Documentation

Real DLLEXPORT_OST_QA ost::qa::ClashScore	(	const mol::EntityView &	ent_a,
		const mol::EntityView &	ent_b
	)

calculate clash score between two entity views

For each atom of ent_a the interaction with atoms of ent_b calculated.

Returns:

0.0 if there are no clashes and a positive clash score otherwise.
