Being an R aficionado, I do the bulk of my work in R and having grown up with Emacs I tend to dislike having to exit my environment to do “other” stuff. This was the motivation for integrating R and the CDK, so that I could access and manipulate chemical information from within my R […]
Chemistry, Clouds, Collaboration (Part 2)
In my previous post I talked mainly about why there isn’t a large showing of chemistry in the cloud. It was based of Deepaks post and a FriendFeed thread, but really only addressed the first two words of the title. The issue of collaboration came up in the FriendFeed thread via some comments from Matthew […]
Chemistry, Clouds, Collaboration (Part 1)
There’s been an interesting discussion sparked by Deepaks post, asking why there is a much smaller showing of chemists and chemistry applications in the cloud compared to other life science areas. This post led to a FriendFeed thread that raised a number of issues. At a high level one can easily point out factors such […]
Faster Maximum Common Substructures
Recently Syed Asad Rahman of the EBI sent around a message regarding some new code that he has been developing to perform maximum common substructure detection. It employs the CDK but also includes some alternative methods, which allow it to handle some cases for which the CDK takes forever. An example is determining the MCSS […]
The Quest for Universal Descriptors – Not There Yet
A major component of QSAR modeling is the choice of molecular descriptors that are used in a model. The literature is replete with descriptors and there’s lots of software (commercial and open source) to calculate them. There are many issues related to molecules descriptors, (such as many descriptors being correlated and so on) but I […]
