Table 2 Benchmarking results for simulated PacBio CLR reads. HC haplotype coverage, ER error rate (mismatches + indels + N’s), MC misassembled contigs proportion. NGA50 is labeled with “-” if the uniquely aligned blocks cover less than half of the reference length. The total sequencing coverage in this table is 20,000 ×. Note that CliqueSNV is a reference-based method, whereas the others are de novo assemblers. For running CliqueSNV, we have tried various strategies (see Additional file 1: Table S2) but only the results of the best strategy are reported here. * If contigs are full-length, this number represents the estimated number of haplotypes or strains in the virus mixture. Wtdbg2 consensus as reference, using reads corrected by Strainline error correction. High quality reference (the highest abundant strain) using reads corrected by Strainline error correction
