Finding recurrent RNA structural networks with fast maximal common subgraphs of edge-colored graphs
Fig 7
Examples of structures to illustrate the three RIN classes.
Those three graphs displayed inside a Venn diagram are subgraphs of Fig 1 with the same SSEs annotations (SSEs D,C and E figured with colored areas). Graph #1 is valid for all three classes. Graph #2 spans over 3 SSEs and so cannot be a valid RINabc. Graph #3 does not contain long-range interactions and thus is only valid for class RINa.
