Uncertainty in NMR based 3D protein models

While I was working on implementing proper author-given chain IDs in PDB structures for Jmol’s mmCIF reader today, I thought it was interesting to mention the recent article Traditional Biomolecular Structure Determination by NMR Spectroscopy Allows for Major Errors by Nabuurs (DOI:10.1371/journal.pcbi.0020009, open access), working at the CMBI, two floors away from my former working location at the Radboud University Nijmegen. 1 minute read

Free online ChemConf 2006 conference

Internet has the nice feature of bringing together people. This has helped many open source projects in the past. But it is also a convenient and cheap way to have conferences. Next month, the ChemConf 2006 conference will be held, and interested people only need to subscribe to a mailing list to participate. less than 1 minute read

InChI's in LaTex and CDK News

An InChI (or see the FAQ) is a line notation for a molecular structure that was recently developed by the NIST and the IUPAC. Principally they can be applied to protein too (see below), but because proteins would give lenghty InChI’s and are quite well defined in terms of connectivity anyway, those can better be described by their amino acid sequence. 1 minute read

The Cologne University BioInformatics Center (CUBIC)

As of April 3, I will be working as postdoc in the group of Christoph Steinbeck at the Cologne University BioInformatics Center, or simply CUBIC, for a year. Though no exact plans have been decided upon, the work will include CDK, CML, ontologies, Bioclipse, semantic web technologies, Jmol, and other interesting things. Research areas will at least include QSAR, but I hope to touch bits of bioinformatics too. less than 1 minute read

How to make money from Open Source scientific software

Dan (the original Jmol author) has an interesting blog series: How to make money from Open Source scientific software I, II and III. Three more blog items are in the planning. The deal with how to make money from open source scientific software. He wants to be able to skeptically review the software in his field, hence open source. But open source software development, at least in chemistry, needs funding, because there are too few people working on such software on a voluntary basis. 1 minute read

The PDB protein database uses Jmol

The beta has been using Jmol as one of the viewers for ages already, but this beta is no longer: it’s the new interface for the PDB database. less than 1 minute read

Open source in drug discovery

Geldenhuys et al. published an article in Drug Discovery Today titled Optimizing the use of open-source software applications in drug discovery (DOI:10.1016/S1359-6446(05)03692-5), and approached the review from a bench chemist point of view. Unfortunately, he discusses free, but closed source, program in one go. less than 1 minute read
