The Speedups Keep on Coming

A while back I wrote about some updates I had made to the CDK fingerprinting code to improve performance. Recently Egon and Jonathan Alvarsson (Uppsala) had made even more improvements. Some of them are simple fixes (making a String[] final, using Set rather than List) while others are more significant (efficient caching of paths). In […]

Do the CDK Fingerprints Work?

In a previous post, I dicussed virtual screening benchmarks and some new public datasets for this purpose. I recently improved the performance of the CDK hashed fingerprints and the next question that arose is whether the CDK fingerprints are any good. With these new datasets, I decided to quantitatively measure how the CDK fingerprints compare […]

Working With Fingerprints in R (can’t beat C!)

Since I do a lot of cheminformatics work in R, I’ve created various functions and packages that make life easier for me as do my modeling and analysis. Most of them are for private consumption.  However, I’ve released a few of them to CRAN since they seem to be generally useful. One of them is […]
