Hi, Thanks a lot for the speedy response. Yes, this is what I was suspecting - slightly different conventions (in this case probably to do with which branch to deal with first) will lead to different results. The book I was referring to is An Introduction to Chemoinformatics from A.R. Lea

Hi all, I am very new to the RDKit and am in the process of running a few test to understand how things are working. One of the first example I have been playing with is the canonical SMILES for Aspirin. This is the piece of code I put together: RWMol *mol=new RWMol(); //Atoms for Aspi

[There's a lot here. I was experimenting with an approach but ended up doubtful, but in need of a good test set. Greg? Is your test data set of 1,000 compounds available? And your fragments? I want to do some experiments of my own. Anyone else? Know any good representative collection of structur
