WebI have a dataset of molecules represented with SMILES strings. I was trying to represent this as graphs. Is there a way to do so? For instance, let's say I have string CC(C)(C)c1ccc2occ(CC(=O)Nc3ccccc3F)c2c1, is there a general way to convert this to a graph representation, meaning adjacency matrix and atom vector?I see questions … WebMay 8, 2013 · Let A be the adjacency matrix for the graph G = (V,E). A (i,j) = 1 if the nodes i and j are connected with an edge, A (i,j) = 0 otherwise. My objective is the one of understanding whether G is acyclic or not. A cycle is defined in the following way: i and j are connected: A (i,j) = 1. j and k are connected: A (j,k) = 1.
