In the following example, it is assumed that the atoms, atomic-form factors, and symmetry operators are well defined. GENErate sets all newly created to one, except for systematic absences, which are indicated by a zero value. The following example also works if there are reflections already present. In this case, GENErate complements the existing reflections so that a full asymmetric unit within the specified resolution limits is produced.
