The header view shows details of Genotype track annotations and filters (figure 13.9). The following information is provided:

Key
The annotation or filter ID.
Export tag

Category
Specifies whether it is a sample/database annotation at the locus/variant/alt variant/haplotype allele/haplotype level, or a filter.

  • NOT_CALCULATABLE - Annotation values can only be stored, not calculated.
  • CALCULATE_AND_STORE - Values are calculated and stored when the track is created.
  • CALCULATE_ONTHEFLY_IF_STORED_VALUE_MISSING - If an element has the annotation, calculate the value on-the-fly if there is no stored value, otherwise use the stored value.
  • CALCULATE_ONTHEFLY_NEVER_STORE - If an element has the annotation, calculate the value on-the-fly when requested.
