SCA
Self-correction approach (SCA) was proposed in the ref (Reducing assembly complexity of microbial genomes with single-molecule sequencin, Genome Biology 2013).
DataSet1
We used all SMRT cells and randomly selected four and six SMRT cells three times for each, and access the correctness by Quast.
