A few days back, Classpath 0.90 was released, the first release after the 0.20 release. Earlier Classpath releases could run the rendering engine , but running the application failed so far . Today it hit Debian unstable, so upgrade my sid32 chroot and had Cacao run Jmol. I had some memory issues opening a small molecule (4-methyl-2-pentyne), and the rendering speed was a factor 100 or so slower than Sun’s JVM, but it runs!
After Kalzium and kfile_chemical , KDE has now be extended with kparts for 3D structure and spectrum display: Kryomol . It is written in C++ and licensed GPL. It supports several chemistry formats, among which quantum chemical formats like Gaussian03, NwChem and ACES, and 3D structures as MDL molefile and XYZ.
With quite some help from Ola (thanx!), I made good progress with the CMLRSS plugin . The current result looks like: A problem in the transition from Jumbo 5.0 to 5.1 is causing a problem so that it does not show a 3D model or 2D diagram, but that will follow soon.
Earlier I already reported that student text books were picking up Jmol as 3D viewer. Now, Nature Structural & Molecular Biology reports (DOI:10.1038/nsmb0206-93) that they picked it up too, using FirstGlance in Jmol (thanx Peter, for reporting this on the Blue Obelisk mailing list!). And, thanx Eric, for acknowledging the hard work of the Jmol developers.
Earlier I reported about postgenomic.com , and needed some diversion from my manuscript work (could no longer think straight about the article I’m working on). So time for some reading up on new technologies. Timing was perfect, because the source code of postgenomic.com got just uploaded to SourceForge SVN.
For the past few weeks I have been working on a review article, which will contain a section with new QSAR/QSPR descriptors published in the period 2000-now.
OpenSource, OpenData and OpenStandards are not as strong in chemoinformatics as they are in bioinformatcs, where it is common knowledge that sharing is a good. Today, the JCIM published on the web an article about the Blue Obelisk movement, which promotes these three idealogies. Several open source projects participate, amongst which the CDK, Jmol, JOELib, OpenBabel, Chemical Markup Language, Bioclipse and Kalzium.
You might have read earlier posts in this blog on CMLRSS, and received a question today on how to integrate CMLRSS with blogs on blogspot.com. Now, current CMLRSS feeds are normally generated with customized scripts, often directly from a database. So, here’s my attempt to include CML in a blogspot.com blog. OpenBabel 2.0 can create good CML, for example for acetic acid: Nothing much to see, right?
Gemma Holiday’s article on CMLReact was published in the january issue of the JCIM (doi:10.1021/ci0502698), which seems to be marked as sample issue right now. She used CMLReact as data format for MACiE (see doi:10.1093/bioinformatics/bti693), a database of 100 enzyme reactions, with fully annotated reaction mechanisms, making this an remarkable and insightfull database.
Roland Krause discussed today in his blog Notes from the Biomass an interesting website: postgenomic.com . This website, still marked BETA, mines blogs in the field of genomics and extract noteworthy statistics from it: which articles are cited in those blogs. For example, the most discussed article is Kai Wang’s Gene-function wiki would let biologists pool worldwide resources in Nature.
I was very pleased to read today that Kalzium, one of the projects that participate in the Blue Obelisk, got awarded! Cheers, Carsten!
