The PLATON subprogram link PLUTON, a decendent of the well known PLUTO program (Motherwell & Clegg), is a molecular graphics tool for the study and display of molecules in their crystallographic environment, producing vector graphics output (X-Windows, Postscript or HPGL) rather than raster graphics. Historically, the algorithms used by PLATON and PLUTON for collecting connected sets of atoms into residues differ to some extent. This may cause some unnecessary confusion. PLATON therefore provides through the PLUTONauto option a path to PLUTON through PLATON that insures consistency of ARU-codes with\ those given in PLATON/CALC listings.
This consistency goal is achieved with the generation of a new input file with extension .eld as an intermediate to be used internally as input for the PLUTON subprogram.
This structural parameter file is saved for optional future use.
In parallel, a file with extension .def is generated. This file contains a set of PLUTON instructions for a default display. The .def file is read after reading the .eld file content.
The PLATON executable may be made to behave as the original standalone PLUTON program in three ways to run with the data file sucrose.spf:
ln -s platon pluton
e.g. pluton sucrose.spf
e.g. platon -p sucrose.spf
