WebIt is not legal in SAM to have a CIGAR string and query sequence with mismatched lengths except for unmapped data, and if we're explicitly stating "CIGAR operations consuming query sequence" then we're simply counting the sequence length via a very contorted fashion. The code even calls this option "min_qlen" internally so it was clearly … WebIt is the score of the max scoring segment in the alignment and may be different from the total alignment score. -u CHAR: How to find canonical splicing sites GT-AG - f: transcript strand; b: both strands; n: no attempt to match GT-AG [n] --end-bonus INT : Score bonus when alignment extends to the end of the query sequence [0]. --score-N INT

I : Insertion (gap in the query sequence). S : Segment of the query sequence that does not appear in the alignment. This is used with soft clipping, where the full-length query sequence is given (field 10 in the SAM record). WebBio::Cigar is a small library to parse CIGAR strings ("Compact Idiosyncratic Gapped Alignment Report"), such as those used in the SAM file format. CIGAR strings are a run-length encoding which minimally describes the alignment of a query sequence to an (often longer) reference sequence. Parsing follows the SAM v1 spec for the CIGAR column. can stress cause food intolerance
