PLATON is free of charge for Academics (as all Academic scientific software should ideally be .....).

For-profit organisations should contact (E-mail address below) or forward a filled out application form (docx) before copying the programs. A PDF version of this form may be found here

Note: All HTTP traffic is logged!

PLATON/UNIX Sources (Fortran & C), executables and test data can be found on the:
PLATON MS-WINDOWS WEB-SITE (Thanks to Louis Farrugia, Glasgow, Scotland)

Note: A Fortran-95 compatible compiler will be needed (e.g. gfortran, ifort).

In order to get a copy of the program source you will have to download (and gunzip) the two files

  1. platon.f.gz (Complete Fortran source of PLATON - about 115000 lines of code)
  2. xdrvr.c.gz (C-interface to X-window library Xlib)
and compile and link them into an executable with the name 'platon' (see example file with the name compile) and when desirable, a soft link of pluton to platon.

Alternatively, download platon.tar.gz which contains all files in the generic 'unix' directory (will compile without any change on DEC, SGI, SUN, Max-OSX and LINUX platforms).


On most UNIX implementations a compile line like the one given below should be sufficient:

gfortran -o platon platon.f xdrvr.c -lX11

Sometimes additional directions should be added on the compile line to indicate the location of libraries such us X11: -L /usr/X11/lib or -L /usr/X11R6/lib.


The platon executable is best moved to a globally accessible directory

e.g. mv platon /usr/local/bin

In addition a link ln -s pluton platon in the same directory will give a direct path to PLUTON.

Some environment variables can be set (for programs etc. that are not in standard locations)

Finally, check whether things work with sucrose.spf. with:

platon sucrose.spf

which should bring up the PLATON Main Selections Menu.

Click on CALC ALL

Three listing files are produced: 'sucrose.lis' (lineprinter format) ,a PostScipt version in A4-format sucrose.lps and a PDF version..
