BNC models of RFP-relevant HCV sites. Nodes in the graph represent 25 nt sites (Table 1) and arcs between them represent relationships. Numbering of nodes in BNC denotes genomic position in Con1 as reference and colour represent genomic region. Node representing RFP is coloured in red. Models learned from HCV sequence profiles sampled from A) non-transplanted patients and from B) transplanted patients are shown.
