6CYANA: distances short - CYANA command

Parameters: atoms=<string>                 (default: *)
            distance=<real>                (default: 9.0)
            structure
            append

This command identifies short-range interatomic distances between atoms
that match the selection and stores them as distance restraints with
zero weight, which are used for "network-anchoring" during automated
NOESY cross peak assignment with the 'assign' command.

The upper bound is set to the maximal value that the short-range
distance can take. Only short-range distances with a maximal distance
shorter than the value of the 'distance' parameter will be stored. If
the option 'structure' is set, then the maximum value of the distance
is set to largest value found in the selected structures. Typically,
these are a bundle of conformers that have no steric overlaps but
otherwise random conformation.  By default, i.e.  if the option
'structure' is not set, the maximum value of the distance is determined
analytically for intraresidual and sequential distances that depend
on up to two dihedral angles, and extended to further intraresidual
and sequential distances by repeated application of the triangle
inequality. The absence or presence of stereospecific assignments is
taken into account when determining the largest possible distance.

By default, the short distances determined by this command will
overwrite any distance restraints that are already in memory. If the
option 'append' is set, the short distances are instead append to
current list of distance restraints.
