Similar Natural Products in NPASS
Similarity level is defined by Tanimoto coefficient (Tc) between two molecules. Tc lies between [0, 1] where '1' indicates the highest similarity. What is Tanimoto coefficient ![](images/questionmark.png)
●  The left chart: Distribution of similarity level between NPC17770 and all remaining natural products in the NPASS database.
●  The right table: Most similar natural products (Tc>=0.56 or Top200).
