What is a CIGAR code in bioinformatics?
The 'CIGAR' (Compact Idiosyncratic Gapped Alignment Report) string is how the SAM/BAM format represents spliced alignments.
Understanding the CIGAR string will help you understand how your query sequence aligns to the reference genome.
For example, the position stored is the left most coordinate of the alignment.Mar 28, 2017.

What is CIGAR format?
"Cigar" (Compact Idiosyncratic Gapped Alignment Report) format is a compressed (run-length encoded) pairwise alignment format.
It is useful for representing long (e.g. genomic) pairwise alignments..
What is the CIGAR alignment format?
CIGAR stands for Concise Idiosyncratic Gapped Alignment Report.
It is a compressed representation of an alignment that is used in the SAM file format.
A CIGAR standard was originally defined by the Exonerate alignment program, but this is not the same as the CIGARs found in SAM files..

What is the CIGAR string in a BAM file?
The CIGAR string is a sequence of of base lengths and the associated operation.
They are used to indicate things like which bases align (either a match/mismatch) with the reference, are deleted from the reference, and are insertions that are not in the reference.Sep 11, 2015.
What is the CIGAR string of the V gene alignment?
The CIGAR string defines the reference sequence as the germline sequence of the given gene or region; e.g., for v_cigar the reference is the V gene germline sequence.
The query sequence is what was input into the alignment tool, which must correspond to what is contained in the sequence field of the Rearrangement data..
- A CIGAR string is made up of \x26lt;integer\x26gt;\x26lt;op\x26gt; pairs, e.g. 76H130M.
Here, "op" is an operation specified as a single character, usually an upper-case letter (see table below).
An operation is usually a type of column that appears in the alignment, e.g. a match or gap. - CIGAR stands for Concise Idiosyncratic Gapped Alignment Report.
It is a compressed representation of an alignment that is used in the SAM file format.
A CIGAR standard was originally defined by the Exonerate alignment program, but this is not the same as the CIGARs found in SAM files. - SAM Format
This is generated by almost every alignment algorithm that exists.
It consists of a header, a row for every read in your dataset, and 11 tab-delimited fields describing that read. - Sequence alignments are useful in bioinformatics for identifying sequence similarity, producing phylogenetic trees, and developing homology models of protein structures.
- The CIGAR string defines the reference sequence as the germline sequence of the given gene or region; e.g., for v_cigar the reference is the V gene germline sequence.
