Reads quality

WebSequencing quality scores measure the probability that a base is called incorrectly. With sequencing by synthesis (SBS) technology, each base in a read is assigned a quality score by a phred-like algorithm 1,2, similar to that originally … Webreads duplicated - number of duplicate reads (flag 0x400 (1024) is set). reads MQ0 - number of mapped reads with mapping quality 0. reads QC failed - number of reads that failed the quality checks (flag 0x200 (512) is set). non-primary alignments - number of secondary reads (flag 0x100 (256) set).
