first of all, thanks a lot for your nice and useful RDKit contribution to KNIME!
I was wondering whether it would be possible to have an extension to the Morgan FP (in particular the FeatMorgan FP):
1) Instead of a hashed fixed sized FP I would rather prefer to have the entire set of found features. I already read here http://tech.knime.org/forum/rdkit/circular-fingerprint-feature-retrieval that you are working on something very similar, if not identical... however,
2)... I would also like to have the frequency of the features.
Strangely, I was always of the opinion that this was already possible with RDKit, but when I now came back to really use it I found it to be different - Maybe it was some other Chemistry Kit. As you already said you are working on point 1), I would be very happy if you could consider my second request!
thanks and keep up the good work!
