Imposes distance difference restraints that favor a symmetric relative orientation of the monomers in a symmetric multimer. The command defines restraints on the difference between corresponding distances between atoms selected by the ''first'' and the ''second'' atom selection. in the monomers of a symmetric multimer. Typically, the ''first'' selection selects a subset of the atoms of the first monomer, and the ''second'' selection selects the corresponding atoms in the second monomer. For each pair of distances between corresponding atoms ''A''/''A''’ and ''B''/''B''’ that match the ''first'' and ''second'' selection, respectively, a term ''w''<sub>ide</sub>(''d''<sub>AB’</sub>-''d''<sub>A’B</sub>)<sup>2</sup> is added to the target function, where ''w''<sub>ide</sub> is the weighting factor defined by the variable '''weight_sym'''. | |||

Description
Imposes distance difference restraints that favor a symmetric relative orientation of the monomers in a symmetric multimer. The command defines restraints on the difference between corresponding distances between atoms selected by the first and the second atom selection. in the monomers of a symmetric multimer. Typically, the first selection selects a subset of the atoms of the first monomer, and the second selection selects the corresponding atoms in the second monomer. For each pair of distances between corresponding atoms A/A’ and B/B’ that match the first and second selection, respectively, a term wide(dAB’-dA’B)2 is added to the target function, where wide is the weighting factor defined by the variable weight_sym.
