JChemPaint project is an editor for 2D molecular structures.

JChemPaint is intended to be complementary to Jmol, a visualisation and analysis tool for 3D molecular structures, started by Dan Gezelter at Notre Dame University, initator of the Open Science Project. and, like JChemPaint, developed by an international team of opensource programmers.

Main features:

  • JChemPaint is open source OS. It is Free Software. We believe that scientific software, especially when its development was publically funded, should be free. As the GNU people put it: "``Free software'' is a matter of liberty, not price. To understand the concept, you should think of 'free speech', not 'free beer.' ". Everyone can participate in the development of the program. Everyone can download and change the source code, provided that he makes the changes publicly available again, according to the GNU Lesser General Public License, LGPL. This ensures that the community can take advantage of any bugfix/enhancement made to the system.
  • It also ensures that a scientist, who needs a standard piece of software like a structure editor as a helper application in her new program, does not have to reinvent the wheel over and over again because all the structure editors that have been written before are now proprietory software. If there is a free structure editor, she can focus on the real science.
  • JChemPaint is not complete :-). Honestly, it can still use a lot of development (see below).
  • Since JChemPaint is written in Java it runs on any computing platform and operating system for which a Java Virtual Machine (of version >= 2) has been implemented (like Linux, Windows 95/98/NT, Solaris, AIX and others).
  • JChemPaint is avaiblable free of charge.
  • JChemPaint is translated into several languages: Dutch, French, German and Polish.
