The "non local environment" (NLE) of one heavy atom
(atom shown in magenta) is defined
as all the heavy atoms, within an Euclidean distance of 7 Å , that belong to an amino
acid that is farther than 11 residues in
the chain (atoms shown in blue) or that belong to another chain (atoms shown in cyan). This is illustrated in
the Figure below.
The atoms shown in red and green are not considered in the calculation. These atoms belong to an
amino acid that is closer than 12 residues in the chain.
An scheme of the non-local environment is provided here.
