distances_set

Parameters

selection=string
(default: none)
bound=string
(default: none)
weight=string
(default: none)
confine=string
(default: none)

Description

This command sets properties of the distance restraints that match the selection string. By default, the selection made in the most recent distances select command is used, or all distance restraints if no selection has been made so far.

Properties that can be set:

  • bound distance bound, given in Angstrom
  • weight relative weight
  • confine confinement limit for violation confinement, given in Angstrom

The value of bound parameter can be an arbitrary real expression that may contain the symbols distance, distdev, distmin, and distmax to denote, respectively, the average value, the standard deviation, the minimal value, and the the maximal value of the corresponding distance in the selected structures.
