SEQ-ANNOT Annotating the Sequence

Other to indicate this relationship. The Nuc-prot set makes this explicit by packaging them together. It also allows descriptive information that applies to all sequences (e.g., the organism or publication citation) to be entered once (see Seq-descr Describing the Sequence, below). 

A Seg set contains a segmented Bioseq and a Parts Bioseq-set, which in turn contains the raw Bioseqs that are referenced by the segmented Bioseq. This may constitute the nucleotide component of a Nuc-prot set. 

An Equiv Bioseq-set is used in the Entrez Genomes division to hold multiple equivalent Bioseqs. Eor example, human chromosomes have one or more genetic maps, physical maps derived by different methods and a segmented Bioseq on which islands of sequenced regions are placed. An aligiunent between the various Bioseqs is made based on references to any available common markers. 

A Seq-aimot is a self-contained package of sequence annotations or information that refers to specific locations on specific Bioseqs. It may contain a feature table, a set of sequence aligmnents, or a set of graphs of attributes along the sequence. 

Multiple Seq-aimots can be placed on a Bioseq or on a Bioseq-set. Each Seq-aimot can have specific attribution. For example, PowerBLAST (Zhang and Madden,
