Many people use "chimeric reads" to describe a type of noise that occur during PCR or sequencing where the bases from two different molecules are reported as one read and the alignments of that read become split when it aligns back to the location of the two original molecules.

WebAn alignment of a read that cannot be represented as a linear alignment. Typically, one of the linear alignments in a chimeric alignment is considered the “representative” alignment, and the others are called “supplementary” and are distinguished by the supplementary alignment flag. 1、Chimeric reads are indicative of structural variation in DNA-seq and it … 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).
