SYMMETRY TOOLS

PLATON HOMEPAGE

Delaunay Cell reduction and search for higher (pseudo) lattice symmetry.

See:
H.Zimmermann & H. Burzlaff, Z. fur Krist. (1985) 170, 241-246
H. Burzlaff & H. Zimmermann, Z. fur Krist. (1985) 170, 247-262

Data required on file x.spf:

TITL text
CELL a b c alpha beta gamma
SPGR space group name (Can be the Laue equivalent)
DELRED (p1 (p2))

and run with the instruction: platon x.spf

Note: (Liberal) default values for p1 and p2 are 0.5 Ang. (tolerance on length) and 1.0 Deg. (tolerance on angle)

Example of 'x.spf' (triclinic to cubic I)

TITL look for metrical symmetry
CELL 10 10 10 109.5 109.5 109.5
LATT P
DELRED

Alternatively, provide a RES, CIF, CSD or SPF structured dataset to PLATON and invoke LEPAGE by clicking on the DELRED button in the PLATON opening menu or with the instruction DELRED from the keyboard interface.
