Symexp is used to reconstruct neighboring asymmetric units from the crystallographic experiment that produced the given structure. This is assuming the use of a PDB file or equivalent that contains enough information (CRYST1 record) to reproduce the lattice.

Symexp creates all symmetry related objects for the specified object that occurs within a cutoff about an atom selection. The new objects are labeled using the prefix provided along with their crystallographic symmetry operation and translation.


# Expand the ''object'' around its ''selection'' by cutoff Angstroms and
# prefix the new objects withs ''prefix''.
symexp prefix, object, selection, cutoff [, segi]

For one protein:

symexp name_for_new_objects,asymmetric_name,(asymmetric_name),distance


  • prefix = string: name prefix for new objects
