Cigar and query sequence lengths differ for
In short, to calculate the query length of a CIGAR string the way that samtools (really htslib) does it, you should add the given length for CIGAR operations M, I, S, =, or X and ignore the length of CIGAR operations for any of the other operations. The current version of the python cigar module seem to be using the same set of operations, and ... WebAug 16, 2024 · Region of the query sequence to use for the search.

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. songs with harlem in the titleWebUSEARCH generates CIGAR strings containing Ms rather than X's and ='s (see below).
