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 … WebAdapter sequences should be removed from reads because they interfere with downstream analyses, such as alignment of reads to a reference. The adapters contain the sequencing … WebSep 15, 2016 · Trimming multiple adapters from each read was also supported previously, but linked adapters make it possible to require that one of them is a 5′ adapter and one a 3′ one. IUPAC ambiguity codes are fully supported.
