Open Babel Paper Published

After much delay, the first academic paper on Open Babel has been published in the open access Journal of Cheminformatics.

http://www.jcheminf.com/content/3/1/33

Over 400 articles using babel have been published, and we discuss the development of Open Babel over the last 10 years, the organization and structure of the code, major features, and highlight a range of interesting uses.

Please consider citing this work if you use Open Babel in a publication.

Pre-registration open for 2nd Open Babble

Pre-registration is now open for the 2nd Open Babble, a hands-on Open Babel workshop presented by Open Babel developers. This will take place on July 5-6 2011 at the Unilever Centre in the Dept of Chemistry, University of Cambridge, UK.

The workshop will start on the afternoon of the 5th July, and finish on the evening of the 6th. The precise topics to be covered will depend on the attendees’ interests but we anticipate covering topics such as how to get the most from the Open Babel command line applications and the GUI, to writing Python scripts and developing software based on the Open Babel library.... read more

Silicos NV contributes Spectrophore code

The upcoming release of Open Babel version 2.3 will incorporate the Spectrophore(TM) descriptor code kindly provided by the Belgian computational chemistry service company Silicos NV.

A Spectrophore(TM) is a descriptor that is derived from the three-dimensional property space surrounding molecules. Properties which are currently included in the calculation of a Spectrophore(TM) include partial atomic charges, atomic lipophilicity values, atomic electrophilicity values, and an atomic shape deviation parameter. Additional atomic properties can easily be added to the code.... read more

Subversion Repository Active

After a few minor hiccups, the Subversion repository is now active, and the old CVS repository has been disabled. The "SVN" access should allow fast, easy access for both developers and regular users alike to the latest code for both development (trunk) and stable branches.

A few useful tips...
