Chimeric reads是什么
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). WebNov 8, 2024 · 1. All chimeric reads with exactly two local alignments are extracted. Reads with more than two local alignments are discarded. 2. If the targetRegion argument is given, chimeric reads must have one local alignment at least overlapping the the target region. If both local alignments are outside the target region, the read is discarded. 3.
