Reads containing adapter
Web(Pair-end sequencing data are plotted together, with the first PE150 bp representing read 1 and the following PE150 bp describes read 2.) Filtering reads containing adapter or with … WebRaw data (raw reads) of FASTQ format were first processed through in-house Perl scripts. In this step, clean data (clean reads) were obtained by removing reads containing adapter, reads containing ploy-N and low-quality reads from raw data. Raw reads were aligned to human reference genome (hg19). Sequencing data were

WebTo trim the adapter we need to provide Trimmomatic with a fasta file containing the adapters we want to remove. For common Illumina adapters, these are provided in the ... The file fastq/trimlog.txt contains a log of what has happened to each and every read. It contains 5 columns: the read name; the surviving sequence length; the location of ... WebJul 2, 2012 · If the two reads in a pair contain adapter sequence the remaining overlapping fragments of genomic origin will be from the same original sequence and can likewise be collapsed into one read and the qualities re-estimated. To collapse two reads into one, AdapterRemoval treats the quality scores for the overlapping region as a position specific ...
WebOct 13, 2016 · Adapter removal is an essential step in computational preprocessing of small RNA sequencing libraries, because only those reads that contain the 3´ adapter are full-length small RNAs and kept for downstream analysis . Many software packages can perform adapter removal with a given 3´ adapter sequence [6–9. We have developed DNApi, a d e …
