PLATON
WHAT IS PLATON/PLUTON
PLATON is a versatile SHELX97 compatible crystallographic tool implementing:
- a large variety of standard geometrical calculations (i.e. bonds, angles, torsions,
planes, rings, inter-molecular contacts (H-Bond analysis), Coordination etc.),
-
tests: (i.e. ADDSYM (building on Yvon LePage's powerful published MISSYM (C) algorithm),
VOIDS etc.),
-
utilities: (cell transformation, SHELXL input etc.), PDB & CIF output
-
graphics: (e.g. automatic labelled 'ORTEP-lookalike plots, the molecular graphics program
PLUTON and NEWMAN plots)
-
several filters: (i.e. Exact (analytical/ de Meulenaer & Tompa) face-indexed
correction for absorption, DELABS (the locally modified Walker & Stuart
DIFABS technique for empirical absorption correction) and SQUEEZE for
handling disordered solvents (= BYPASS procedure, (v.d. Sluis & Spek,
Acta Cryst. (1990), A46, 194))).
Validation checks for data supplied in CIF-Format.
Most PLATON features complement those available in the widely distributed
public domain SHELX97 package.
Note: Most features are currently available only for non-protein structures.
PLATON may be obtained by anonymous.ftp or by http://www.cryst.chem.uu.nl/platon/
