G4 cluster search and visualization. (A) The G4 cluster browser. Each cluster is identified by a unique identifier and is annotated by the number of associated genomes, the number of G4 sequences (total, by regular expression or G4Hunter), and, finally, the presence or absence of a 3D representative. (B–D) An example G4 cluster entry page (ID: G4C-0084453). The entry contains the basic cluster metadata, as well as the taxonomic distribution of its contents (B). In addition, interactive viewers are given for the cluster's MSA, HMM (in the form of a sequence logo), representative sequence (C), and, if available, 3D structure representative conformation (D).
