Hi, Greg, Thank you for your quick reply. I've been using RDKit since your poster presentation in SHEF2010. RDKit is very powerful and light cheminformaticsn tool. I hope the function is available in the next spring. Best, Takanori Ohgaru. 2010/12/27 17:54 "Greg Landrum" : Hi, 2010/12/27 大軽 貴典

I was surprised that, using topological fingerprints, the tanimoto similarity between benzene and toluene is 0.32 Examining the fp bits, I can see why. But I don't understand why so many paths are repeated for toluene. To my way of thinking, paths that trace the same types of atoms should not be c

HI Greg Thanks for the quick reply. Sure enough, the latest version of rdkit fixes the problem I was having. I should have tried that first! Now that I have the build issues worked out, a svn update and make install is pretty quick. TJ On Sun, Dec 26, 2010 at 8:31 PM, Greg Landrum wrote: > Hi

I use RDkit RDKit_2010_09_01 I've got ECFP_X-like Morgan fingerprint of compounds. The following code is an example. fp = rdMolDescriptors.GetMorganFingerprint(m,4) dic = fp.GetNonzeroElements() for key in dic: I would like to know which fragment corresponds to each key. Is there any methods to
