I added a Bioclipse plugin for JOELib (GPL, by Joerg) which comes with many QSAR descriptors, several of which are now available in the QSAR feature of Bioclipse : Meanwhile, the Bioclipse team in Uppsala has set up the obligatory scatter plot functionality, but leave that screenshot for them to show. Therefore, time for integration with R.

The Open Data/ChemSpider debate is continuing, and Noel wondered in the ChemSpider Blog item on the Open Data spectra in ChemSpider. The spectra in ChemSpider come from four persons, two of which released their data as Open Data (Robert and Jean-Claude) and two as proprietary data.

On my way back from the Taverna workshop I visited Nature HQ, as Ian reported about on Nascent. It was a (too) short meeting, but very nice to meet Euan (finally;

A molecular structure without any properties in meaningless. Structure generators can easily build up a database of molecules of unlimited size. 30 million in CAS, 20 million in ChemSpider or 15 million in PubChem is nothing yet. The value comes in when linking those structures with experimental properties.

CompLife 2007 was held 1.5 weeks ago in Utrecht, The Netherlands. The number of participants was much lower than last year in Cambridge. Ola and I gave a tutorial on Bioclipse, and Thorsten one on KNIME.

I value ODOSOS very high: they are a key component of science, and scientific research, though not every scientist sees these importance yet. I strongly believe that scientific progress is held back because of scientific results not being open; it’s putting us back into the days of alchemy, where experiments were like black boxes and procedures kept secretly.

The second part of the morning session featured a presentation by Sirisha Gollapudi which spoke about mining biological graphs, such as protein-protein interaction networks and metabolic pathways. Patterns detection for nodes with only one edge, and cycles etc, using Taverna.

I arrived at the EBI last night for the Taverna workshop, during which the design of Taverna2 is presented and workflow examples are discussed. Several ‘colleagues’ from Wageningen and the SARA computing center in Amsterdam are present, along with many other interesting people. This afternoon is my presentation.

Peter is writing up a 1FTE grant proposal for someone to work on the question how automatic agents and, more interestingly, the blogosphere are changing, no improving, the dissemination of scientific literature. He wants our input.

Craig James wants to make SMILES an open standard, and this has been received with much enthusiasm. SMILES (Simplified molecular input line entry specification) is a de facto standard in chemoinformatics, but the specification is not overly clear, which Craig wants to address. The draft is CC-licensed and will be discussed on the new Blue Obelisk blueobelisk-smiles mailing list.

Pierre pointed me to Google’s view:timeline feature, which shows the search results on a time line, by recognizing phrases like “on 25 September 2000…”. This is its view on the Chemistry Development Kit:
