6CYANA: library replace - CYANA command

Parameters: selection=<string>             (default: <blank>)

This command replaces for the atoms matched by the selection <string>
the coordinates of the corresponding residue entry in the residue
library entry by the coordinates of the current structure. By default,
the selection made in the most recent 'atoms select' command is used,
or all atoms if no selection has been made so far.

The coordinate replacement takes place only for residues for which the
atom selection includes all atoms of a residue entry in the residue
library, including possible "overlap" atoms with the preceding and
following residue. For instance, in the case of amino acid residues
the atoms C and O of the preceding residue, and N of the following
residue). The coordinates of the first matching residue in the current
structure are used.
