WebA Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing. It was originally developed for the computer program Phred to help in the automation of DNA sequencing in the Human Genome Project.Phred quality scores are assigned to each nucleotide base call in automated … Web7.3. Filtering and trimming reads. Based on the results of the quality check, you may want to trim or filter the reads. The quality check might have shown the number of reads that have low quality scores. These reads will probably not align very well because of the potential mistakes in base calling, or they may align to wrong places in the genome. WebTo reduce the number of falsely trimmed bases, the alignment algorithm requires that at least three bases of the adapter are aligned to the read. This minimum overlap length can be changed globally (for all adapters) with the parameter --overlap (or its short version -O ).
