Paired-end reads是如何拼接的

WebWhen performing sequencing on an Illumina instrument, sequences corresponding to the library adapters can be present in the FASTQ files at the 3’ end of the reads if the read length is longer than the insert size. To remove these sequences and prevent issues with downstream alignment, adapter trimming is an option in Illumina FASTQ generation … WebShort-read algorithm: alter the read sequence such that it matches the reference exactly. Long-read algorithm (BWA-SW): sample reference subsequences and perform Smith-Waterman alignment between the subsequences and the read.
