Measurements and quantities

Keep a measured value with its unit, uncertainty, and source. Capture quantities without silently converting them.

• Measurement value. A supplied scientific reading with units, symmetric uncertainty, optional scientific notation and explicit availability.
• Quantity field. A 44px Vlak numeric input and styled unit selector with controlled quantity values, form submission and reset support.

Experimental work

Select a sample position, follow an experimental run, and inspect a spectrum alongside the underlying values.

• Experiment run. Supplied experiment metadata, conditions and ordered protocol steps with explicit statuses and controlled recording actions.
• Spectrum plot. A supplied numeric spectrum with labelled axes, caller-provided peak annotations and a complete paginated data table.

Microscopy

Review named stage positions in an explicit coordinate frame, navigate supplied stacks and edit acquisition sequences with declared units.

• Stage position list. Reviews supplied named stage positions with an explicit coordinate frame, per-axis units, inclusion state and controlled selection, reorder and removal requests.
• Stack navigator. Navigates supplied depth, time, channel and stage-position axes while preserving exact physical readings and indexed positions.
• Acquisition sequencer. Edits supplied capture steps, exact exposure, time, depth and channel values, and distinguishes requested actions from recorded run state.

Genomics

Enter a genomic region, inspect supplied sequence alignments and compare exact coverage counts.

• Genomic region field. Collects a reference, contig and validated integer interval with an explicit one-based inclusive coordinate convention and native form submission.
• Sequence alignment. Displays a bounded window of already aligned reference and read strings, with supplied genomic positions, gaps and keyboard region selection.
• Coverage inspector. Shows supplied per-locus depth, base and strand counts with an exact position selector, bounded plot and complete depth table.

Keep coordinate conventions explicit

Genomic regions and supplied loci use 1-based inclusive coordinates. Alignment selections use 1-based aligned columns, including supplied gap columns. Stack values are zero-based indexes into supplied positions; the displayed ordinal starts at one. Stage positions retain immutable identifiers, supplied frame identity and per-axis units; missing coordinates are not zero. The host owns coordinate conversion and reference identity.

Preserve measurement meaning

Supply the unit, uncertainty label, precision, and provenance that belong to the measurement. A missing value is distinct from zero. The application owns significant-figure rules and scientific interpretation.

Convert explicitly

QuantityField changes the selected unit and amount independently. It does not convert units. Perform validated conversion in the application and update the complete controlled value together.

Keep instrument work outside the view

Stage selection requires controlled value and onValueChange props. Inclusion, order, removal and experiment actions request changes; the host supplies accepted records. Selection never confirms stage motion or acquired frames. The application controls instrument access, execution, persistence and confirmed step status.

Show the evidence behind a plot

Supply finite points, axis labels, units, and any peak annotations. SpectrumPlot provides a data table and does not identify substances, fit peaks, or infer scientific conclusions.
