I’ve been working on the rcdk and rcdklibs R packages that integrate the CDK into the R environment. For the past year or two it’s been hosted on r-forge.r-project.org which has a nice feature of nightly builds of R packages. Unfortunately their version control system is Subversion. Having used Git for my other projects, this was […]
RNAi in PubChem

These screens reuse the PubChem bioaassay formats – which is both good and bad. For example, while there are a few standardized columns (such as PUBCHEM_ACTIVITY_SCORE), the bulk of the user […]
What Has Cheminformatics Done for You Lately?
Recently there have been two papers asking whether cheminformatics or virtual screening in general, have really helped drug discovery, in terms of lead discovery. The first paper from Muchmore et al focuses on the utility of various cheminformatics tools in drug discovery. Their report is retrospective in nature where they note that while much research […]

While the location is certainly an attraction, there was some pretty nice talks and symposia in the CINF division such as the Visualization of Chemical Data, Metabolomics and Materials Informatics. Credit for these (and all the other) symposia go to the organizers […]
