A toy example of a reads tree that stores AAAGA, AAAGC, and AACT. There are as many (different) sequences as accepting nodes. The first read, AAAGA, starts from the first element of the array, indexed by 0, which maps to AAA (using the usual encoding: A = 0, C = 1, etc.). In order to complete the read, we follow the arrow to node G, then accepting node A
