Description: An Interval represents a span of sequence. Positions are always represented by contiguous spans using interbase coordinates.

This definition of Interval is intended to be compatible with that in Sequence Ontology (SO:0000001), with the exception that the GA4GH VR Interval may be zero-width. The SO definition is for an “extent greater than zero”.

Interval Value Example

{
   "end" : "22",
   "start" : "11",
   "type" : "SimpleInterval"
}
