WebbThere is a large number of ring finding algorithms. Many have the goal of finding a "smallest set of smallest rings", so are called an SSSR algorithm. Frequently the easiest way to get the ring count from a toolkit comes as a direct consequence of computing the SSSR. Note though that ring identification is not necessary for this task. WebbSearches in the /SZ, /EA, and /ES fields retrieve only ring systems containing the specified set of small rings. They do not retrieve ring systems in which those small rings are part of larger ring systems. Use the following search fields if …
Webb1 feb. 1976 · Since a ring system can have many different sets of rings which describe it equally well, it is customary to characterize a ring by the smallest set of smallest rings … WebbIt is been a while since I've studied chemistry. Now, I am reading the documentation of RDKit, where they mention the expression "smallest set of smallest rings" (SSSRs). I understand that a ring is a cycle in a molecule. I also understand that the SSSRs is, as the name suggest, the smallest set of smallest rings, but how do you determine what the …
