"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. " - Low-quality bases
