Hello folks, First of all, sorry about starting a new thread. Unfortunately, I have not figured out a way to reply to my own earlier post.
I have found the answer to this ReplaceSubstructs issue from Paolo's reply to an earlier post of mine. https://sourceforge.net/p/rdkit/mailman/message/37372865/ Although I asked a different question on that post, the answer to my current question is embedded there. Thank you Paolo. The reason that sometimes one piece is returned and sometimes two pieces are returned is that "only the bond between first atom in the uniquified match and the remainder of the molecule is restored" However, I would still appreciate if someone could suggest some work around to my "DeleteSubstructs" post. Thanks.
