a Each node stands for k-mer. Four blue nodes represent the k-mers chosen from the head part of reads which are related to donor, while four green nodes represent the k-mers from the tail part which correspond to acceptor. Two purple nodes with symbol # represent the quality control nodes. Two self-circle cases and two regular-circle cases are found by the combination of donor and acceptor candidates. b Check whether or not quality control nodes support each circular case. c “Regular-Circle Candi 1” and “Self-Circle Candi 2” are kept, since they are supported by more quality control nodes than others in their case group respectively
