In this case, polyG tail trimming will be applied first since polyG is usually caused by sequencing artifacts and should be trimmed first. Results are listed in Table 1. 2015 Jun 6;10:62. doi: 10.1186/s13000-015-0296-y. This information is quite useful for diagnosing sequence quality issues. Duplication level evaluation is important to profile the diversity of the sequencing libraries. KEGG Database - Genome Our aim is to catalogue the current scholarly information sourced from across For paired-end data, if one pair of reads can be detected with a good overlap, then the bases within the overlapped region can be compared.
