NAME
     SetNeigh - set sheet neighbours of residues

SYNOPSIS
     SetNeigh expr expr expr expr

DESCRIPTION
     Set the information about neighbouring residues used
     for schematic display of beta sheets. The arguments
     are applied to all selected molecules.

     The first and second argument give the numbers of the
     start and end residues in the first strand, where the
     start number must be smaller than the end number. The
     third and fourth argument give the start and end
     numbers of residues in the second strand. For a
     parallel pair of strands, the start number must be
     smaller than the end number, for an antiparallel pair
     it must be larger. Both strands must have the same
     number of residues and must not overlap.

     This command is only used if the secondary structure
     information was not read from a PDB file or calculated
     with CalcSecondary, or if the user wants to modify
     this information.

EXAMPLE
