Subset selection: mind the complexity

In a recent JCIM article, Schuffenhauer compares a few subset selection methods, and notes that some of them reduce the average complexity of the molecules. They put this in relation to other research that states that lead compounds with high complexity have higher activities. Recommended reading material for the holidays. less than 1 minute read

I drop in on the #classpath channel of freenode.net IRC network, where the #cdk channel runs too. The #classpath channel is for the Classpath project which is developing the free Java libraries used by most open source virtual machines. 1 minute read

Jumbo 5.0 and the CDK

I reported earlier that the CDK has been updated in CVS to use CML from the new Jumbo 5.0. The transition actually involved a lot of changes in the CDK, some I would like to address in the following comments.

This is how this is done. 3 minute read

Tobias commited Jumbo 5.0 to CDK CVS, so that the CDK is now again up to date with the latest CML library. Note that Jumbo 5.0 requires Java 5.0. less than 1 minute read

UML diagram of CDK module dependencies

The code clean up after CDK’s interfaces transition is in progress, and two CDK modules are now independent of the data module. After doing the core module , the standard was next, and I finished this yesterday. The dependencies in CVS now look like (click it to get a larger view): 1 minute read
