PLATON

WHAT IS PLATON/PLUTON

• 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))).

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.
