I'm producing MACCs keys with the "RDKit Fingerprint" node, and I am noticing that I am getting 167 bits instead of 166. The node description acknowledges that there should be 166 bits for MACCs. Not sure where this extra bit could be coming from.
Also, the "Fingerprints" node (from CDK) gives the correct number of bits.
Does anyone know where I might be able to learn more about and/or fix this issue?
