BLSOM for 7-mers. a BLSOM and heatmap. The total number of nodes was set to 1/50 of the total number of viral genomes. (i) Nodes are colored as described in Fig. 1. (ii) The top panel shows the GH territory (
) on the BLSOM. The middle and bottom panels show heatmaps of UAGCGCU and GAGCGCU, respectively, which differ only in the underlined base. b BLSOMs for 255 different 7-mers. Nodes are colored as described in Fig. 1. c BLSOMs for 377 different 7-mers. (i) Nodes are colored as described in Fig. 1. (ii) The top four panels show the four different territories colored as described in Fig. 1. The middle and bottom panels show heatmaps of four pairs of 7-mers with a one-base difference
