There are a large number of methods for handling the convertion of between 1D line
notations like SMILES , 2D depictions for papers and documents and 3D molecular
configurations for modelling and property calculations. One of the best source of
these utilitiies is the Daylight with their Programming tool-kits and applications.
For quick creation of 3D configurations for 3D chemical database searching and
starting points for MOPAC and other calculations are are a number of commerical tools
:-
Concord Tripos USA
Rubicon Daylight see http://www.daylight.com
Chem-X Chemical Design limited UK
CACTVS see http://schiele.organik.uni-erlangen.de/cactvs
(free convertion service for a small number of structures via the WWW)
There creation of smiles codes from 2D depictions is handled by ChemDraw, ChemWindows
and many other chemical drawing programme. There CACTVS system contains a good free
graphical editor for creations of smiles on some common unix platforms.
The ability to convertion of Smiles to 2D depictions is less common. There Daylight
WWW page http://www.daylight.com provides a simple Web page for this. The following
tools are also available for the PC environment.
Consisant Exographics USA
Accord Synopics UK
Unity Tripos USA
Depict-Toolkit Daylight
The Best utility I have found for the general conversion between the various 2D
formats Babel released by the Dept. of Chemistry, University of Arizona,Tucson, AZ
