The Header section of a BAM-file consists of the header line and the Reference sequence dictionary. The header line contains information about the format version and a specification of the sorting order of alignments. The reference dictionary contains information about the name and the length of each reference sequence. The bamHeader object can be used to initialize an object of class bamWriter. The bamHeaderText can be used to inspect the content of the header.
