Class

vcfc:ContigHeaderLine

A structured '##contig=<...>' declaration for a reference sequence used by records in the file. VCF 4.5 requires its ID and reserves optional attributes such as length, md5, and URL; contig declarations are recommended in VCF and required in BCF.

Relation	Target	Target Description
Subclass Of	`vcfc:StructuredHeaderLine`	A VCF meta-information line whose value is an angle-bracketed, comma-separated list of key-value attributes. Implementations must not rely on the source attribute order, but may preserve it with vcfc:attributeIndex.

Incoming Relationships

Terms that point at this term in the generated relationship graph.

Relation	Source	Source Description
Range	`vcfc:chromosome`	Links a record to the declared contig corresponding to its CHROM value. The CHROM column identifies a reference sequence (or, for breakpoint assemblies, an angle-bracketed assembly contig ID); a resolvable external reference may also be aligned to FALDO.
Domain	`vcfc:contigId`	The required ID attribute of a '##contig=<...>' declaration. It names the reference sequence that may be cited in CHROM and must not be a reserved symbolic-allele name.
Domain	`vcfc:contigLength`	The optional 'length' attribute of a contig declaration: the length of the reference sequence in bases.
Domain	`vcfc:contigAssembly`	An optional assembly identifier supplied in a contig declaration. It identifies the reference assembly context for the named contig.
Domain	`vcfc:contigMd5`	The optional 'md5' attribute of a contig declaration: the lowercase hexadecimal MD5 checksum of the normalized reference sequence, as defined by the SAM specification and referenced by VCF 4.5.
Domain	`vcfc:contigUrl`	contig URL
