About two weeks ago, the ChemConnector blog reported an InChIKey collosion detected by Prof. Goodman. Unlike the previous collision, this one was based solely on the graph and not on stereochemistry. The two molecules both have the InChIKey OCPAUTFLLNMYSX-UHFFFAOYSA-N: The compounds are really different, the molecular formulas are C 50 H 102 O and C 57 H 114 O respectively.

Web of Science is my de facto standard for citation statistics (I need these for VR grant applications), and defines the lower limit of citations (it is pretty clean, but I do have to ping them now and then to fix something). The public front-end of it is Researcher ID. There is an Microsoft initiative, which looks clean but doesn’t work on Linux for the nicer things, but the coverage of journals is pretty bad in my field, giving a biased

I cannot find the bug report just now, but the CDK has an open problem with change even notification, where the nonotify classes still caused change event to be sent around. This was because the nonotify classes extended in a wrong way the data classes. So, I worked today on copying the data class implementations into a new implementation, not extending the data classes, while removing the listener code: the silent module.

Kasabi is a new, RDF hosting service by Talis. It’s still in beta, and I have been testing their beta service with the RDF version I created of ChemPedia Substances (the now no longer existing cool web service from MetaMolecular to draw and name organic molecules). Kasabi makes the RDF data available via a few APIs, depending on the APIs selected by the uploader. I picked all five of them, just to see how things work.

Update 2021-02 : this post is still the second-most read post in my blog. Welcome! Some updates: Ammar Ammar in our BiGCaT group has set up a new SPARQL endpoint. Please use and tweet. blog, or otherwise let others now how you use the ChEMBL RDF. Since this post I have blogged a lot more about ChEMBL. Update : this work is now written down in this paper. I’m having a really bad month, as you can see from the number of posts.

Some time ago, the brilliant GitHub people gave me the following tip. Rajarshi is lazy, and might find it interesting. By appending .patch to the commit URL, a commit can easily be downloaded as patch. That way, developers can easily download it with wget or curl and apply it locally with git am, without having the fetch the full repository.

Last month I reported a few things I missed in CiteULike. One of them was support for CiTO (see doi:https://doi.org/10.1186/2041-1480-1-S1-S6), a great Citation Typing Ontology. I promised the CiTO author, David, my use cases, but have been horribly busy in the past few weeks with my new position, wrapping up my past position, and thinking on my position after Cambridge.

AJCann posted a blog today about what he doesn’t like about Mendeley. Abhishek replied that he does not like people complain about one tool, instead of pointing out a good alternative. Mendeley has two alternatives, Zotero and CiteULike (there is also Connotea, but got behind in evolution). Agreeing with @citeulike and @abhishektiwari, as a service provider any bad news is good news too: they provide opportunities to improve.

I have blogged about two Molecular Chemometrics principles so far: McPrinciple #1: access to data McPrinciple #2: be clear in what you mean Peter’s post #solo10: Green Chain Reaction; where to store the data? DSR? IR? BioTorrent, OKF or ??? gives me enough basis to write up a third principle: Molecular Chemometrics Principles #3 : We make scientific progress if we build on past achievements. Sounds logical, right?
