RowPredicate

Auto-generated from the config schema in the source — see the config guide for concepts. Built into JBrowse core. View source.

One entry of rows.filter: a FieldPredicate over a row attribute, a samplesTsv column on the variant display, a subtrack field on wiggle, group on the mark displays. A row's name, its sample, its source, its haplotype, its label and its colors are refused, since they name a row rather than describe it: a row's name goes in rows.kept. So is a jexl: field, which a row has no record to compute over. A row missing the attribute (absent or empty) fails every test but valid: false, which selects exactly those rows.

Example usage#

{ type: 'LinearVariantDisplay', rows: { filter: [{ field: 'population', oneOf: ['EUR', 'AFR'] }] } }
