WebRead bases that do not match are color coded, and insertions and deletions within reads relative to the reference are marked. Insertions are indicated by a purple I and deletions are indicated with a black dash (–). In addition, mismatched bases are assigned a transparency value proportional to the read quality known as the phred score. This ... Webtion of the reads being unusable, resulting in wasted time and expense. PhiX quality scores for the MiSeq ® and HiSeq systems show that nearly all bases have scores > Q30 for single and paired-end reads (Figure 2). Comparison of E. coli whole-genome sequencing data shows that this high data quality is consistent across both platforms (Table 2).
