[Rdkit-discuss] compatibiltiy between parallel python and rdkit

Hello, I am relatively new to rdkit but have found it to be very useful in creating compounds with the reaction functions. Currently my project involves taking a handful of scaffolds and creating shrubbery for these scaffolds based on available precursor compounds. I found that creating more

This is not a bug nor a feature per se. You need to set the compounds as PropteryMOl Ie Ketone = [x for x in supplAlkylKetones if x is not None] for i in range(len(Ketone)): Ketone[i] = PropertyMol(Ketone[i]) From: Maciek Wójcikowski [mailto:mac...@wojcikowski.pl] Sent: Friday, March 18,

Hello, I have seemed to hit a wall with what seems like a simple task. First, I have ~9800 compounds that have a primary amine for a reaction that I am completing in rdkit. About 250 of those compounds have a tertiary alkylamine that is most likely protonated at pH 7.4. The dataset is a set
