This has already been posted on some mailing lists, but one more place can’t hurt. The International Conference on Chemical Structures (ICCS) is coming up in June, 2011 at Noordwijkerhout, The Netherlands. I’m on the scientific advisory board and am planning to attend this meeting, as the topics being covered look pretty interesting, especially those focusing […]
Visualizing PAINS SMARTS
A few days ago I had made available a SMARTS version of the PAINS substructural filters, that were converted using CACTVS from the original SLN patterns. I had mentioned that the SMARTSViewer application was a handy way to visualize the complex SMARTS patterns. Matthias Rarey let me know that his student had converted all the […]
Similarity Matrices in Parallel
Today I got an email asking whether it’d be possible to speed up a fingerprint similarity matrix calculation in R. Now, pairwise similarity matrix calculations (whether they’re for molecules or sequences or anything else) are by definition quadratic in nature. So performing these calculations for large collections aren’t always feasible – in many cases, it’s […]
