WebThe .flagstat file provides read counts for each of 13 categories based primarily on bit flags in the FLAG field. Each category in the output is broken down into QC pass and QC fail. In the default output format, these are presented as "#PASS + #FAIL" followed by a description of the category. WebThe primary mapped count is a percentage of the total number of QC-passed and QC-failed primary reads. In the tsv and json formats, these percentages are listed in separate categories mapped %, primary mapped % , properly paired %, and singletons %.
WebDec 21, 2015 · Primary Alignment and Secondary Alignment: A read may map ambiguously to multiple locations, e.g. due to repeats. Only one of the multiple read alignments is considered primary, and this decision may be arbitrary. All other alignments have the secondary alignment flag. 5 How to filter those reads?
