Built-in track kinds

A track’s kind says what it is in domain terms — features, variants, a confidence ramp — and ProtVista maps it to the right renderer and data adapter for you. Write kind: features, not a component name.

This page lists every built-in kind. For the exact data shape each one consumes, see the Adapter reference; for the boundary between what your config controls and what the data must provide, see Configuration vs data.

The kinds

kind	What it draws	Typical data
features	Sequence feature regions (domains, chains, binding sites, signal peptides…) drawn as shapes along the sequence.	UniProt features API, or your own CSV/TSV/JSON/BED.
features-interpro	InterPro domain and family predictions.	InterPro entries API.
variants	Single-residue variants (amino-acid changes), with disease association.	UniProt variation API.
variant-counts	A line graph of variant frequency along the sequence.	UniProt variation counts.
rna-editing	RNA-editing sites, drawn like variants.	UniProt RNA-editing API.
rna-editing-counts	A line graph of RNA-editing frequency.	UniProt RNA-editing counts.
peptides	Mass-spectrometry-detected peptides.	UniProt proteomics API.
peptides-ptm	Post-translational modifications detected by MS.	UniProt proteomics PTM API.
structure-coverage	Which stretches of the sequence are covered by known 3D structures.	UniProt/PDBe coverage.
confidence-score	AlphaFold per-residue confidence (pLDDT), drawn as a colour gradient over the sequence.	AlphaFold prediction.
pathogenicity-score	AlphaMissense average pathogenicity per residue, as a colour gradient.	AlphaMissense average.
pathogenicity-heatmap	AlphaMissense pathogenicity as a full heatmap (every substitution × position).	AlphaMissense full matrix.

Colour scales

The score kinds (confidence-score, pathogenicity-score) come with accessibility-reviewed colour ramps built in — AlphaFold’s confidence ramp (orange = low confidence, through to blue = very high) and AlphaMissense’s benign-to-pathogenic scale (blue = benign, through to red = pathogenic). You can define and apply your own ramps; see Theme the viewer and Escape hatches (registerTheme).

Using a kind with your own data

Most kinds default to an EBI/UniProt API, but features is the one you’ll most often point at your own file — its data is the generic feature record (type, start, end, and optional description/score). See Load your own data.
