Item Description
The tendency of the group of atoms (e.g. residue
or ligand, side chain, main chain) to move away from its current position.
Displacement of atoms from electron density is estimated from the
difference (Fobs - Fcal) map. The displacement vector is the ratio of
the gradient of difference density to the curvature. The amplitude of
the displacement vector is an indicator of the positional error.
