We are progressing well on our work on the InChI Resolver that we are collaborating on with the RSC to deliver. We’ve published millions of structures, InChIs, InChiKeys, StdInChIs and StdInChIKeys. We’ve built the web services to generate and resolve InChIs and are well on our way to delivering the system before ACS Spring 2009.

One thing we want to provide is the ability for people to draw a molecule and submit it to both generate the list of InChIs/Keys as well as to resolve. In order to do this we are looking for either a web-based structure drawing tool. We welcome any offers to contribute a structure drawing tool for the good of the community. Please feel free to post a comment here or contact me offline. Thanks

    As you suggested in FF, JChemPaint might be a good option, as the new version is increasingly configurable.

    In general, JChemPaint is not the only opensource alternative. There is Duan JavaScript editor (under development), and MX, a small GPL-ed applet published recently in Molecules 2006, 11, 129-141.

    Importantly… please write down the functional requirements… just simple organic molecules? Do you need charges, isotope information, radicals?

    I think Marvin will be fine here, unless it must be open source.

    At this time we understand Marvin is the highest performance native web ready structure/reaction/query editor/viewer available and we have some positive news that it approaches the highest performance for desktops. Marvin can be used freely for non commercial/freely accessible (no login) webpages.

    Major features and links to user and dev manuals and code examples see here: http://www.chemaxon.com/product/msketch.html


    If you have a wheel already, then let’s roll.
