Excel messes up your data analysis :)

Well, no wonder: Excel is meant to be used to process money flows. Anyway, greyarea pointed me to this nice blog item from March 2006. It discusses a 2004 article in BMC Bioinformatics Mistaken Identifiers: Gene name errors can be introduced inadvertently when using Excel in bioinformatics by Barry Zeeberg et al. (DOI:10.1186/1471-2105-5-80). Hence, the importance of semantics and proper markup languages. The quotes are illustrative: 1 minute read

RDF-ing molecular space

RDF might be the solution we are looking for to get a grip on the huge amount of information we are facing. microformats, and RDFa, are just solutions along the way, and Gleaning Resource Descriptions from Dialects of Languages (GRDDL) might be an important tool to get the web RDF-ied. 2 minute read

Further Bioclipse QSAR functionality development

I had some time to work some more on the QSAR functionality in Bioclipse. There is still much to do, but it is getting there. The calculation of a QSAR descriptor data matrix less than 1 minute read

Screencasts for life science informatics

Deepak blogged about screencasting for bio topics, concentrated at bioscreencast.com of which he is co-owner. I guess it is like a YouTube for bioinformatics thingies. Jean-Claude picked this up very quickly (seen on Cb? At least I did.), and already uploaded a screencast, demoing JSpecView written by Robert. I wonder if he will upload the screencasts he made for Bioclipse too? (hint, hint … :) less than 1 minute read

The CDK data model #1

The Chemistry Development Kit has a rich set of data classes, each of which is defined by an interface. While the classes for atoms, bonds and a connectivity table are fairly straightforward, but beyond that it is sometimes not entirely clear. I will now discuss all interfaces in a series of blog items. I’ll start with the IChemFile. Christoph, please correct me if I move to far away from our Notre Dame board sketch. 2 minute read

The Open Science Notebook 10 years ago

So, with all these people blogging about the Open Science Notebook (yes, each word is one distinct blog) it is worth looking back in time. To make clear what I put under the OSN: a notebook in which experimental details and outcome are written down. So, what did the OSN look like almost ten years ago? 1 minute read
