Use this file to discover all available pages before exploring further.
Click any dataset in the list to open its detail page.
The header shows:
- The dataset name with a version badge (e.g.,
v2)
- An optional description (click the pencil icon to edit)
- Metric cards: Samples, Features, Version, and Sensor
The name and description are the only fields you can edit after creation. Everything else is frozen.
Top-right actions
| Button | What it does |
|---|
| Download | Opens a dropdown with Download as JSON or Download as Excel |
| New Version | Creates a new version of this dataset, capturing fresh data from the same sensor |
Tabs
The detail page has five tabs.
Spectra
Shows all spectra in the dataset overlaid on one chart, with the sensor’s units on the axes.
This tab is useful for a quick visual sanity check: do the spectra look as expected? Are there any visible outliers in the snapshot?
Samples
A searchable, paginated table of every sample in the snapshot, with columns for each property.
| Action | Result |
|---|
| Click a row | Opens a modal showing that sample’s spectrum, all property values, and metadata |
| Search | Filters by sample name |
| Page size | 25, 50, or 100 per page |
Properties
Distribution statistics for every property in the snapshot. Same layout as the Data Explorer Properties tab:
- Continuous: mean, median, std, min, Q1, Q3, max, plus histogram and box plot
- Categorical: bar chart of category counts
This is the snapshot’s view: numbers reflect the dataset, not the current state of the project.
Sensor
Metadata for the sensor used to create the dataset. Includes:
- Name and description
- Manufacturer and model
- Type (NIR, FTIR, etc.)
- Units (x and y)
- Number of data points
- X-axis range (min and max)
- Creation date and creator
- Any custom fields
This is a copy of the sensor at snapshot time. Even if you edit the sensor later, the dataset shows the original.
Versions
A table of every version of this dataset, including the current one (highlighted).
| Column | Description |
|---|
| Version | Version number (v1, v2, …) |
| Description | The “what changed?” note from when the version was created |
| Samples | Sample count at that version’s snapshot time |
| Features | Feature count |
| Created by | User who created the version |
| Created | Timestamp |
Downloads
Both download formats include the same data, packaged differently.
Download as JSON
A single .json file containing:
- Dataset name, description, creation date
- Sensor metadata
- The full wavenumber/wavelength array
- Per-sample blocks: spectrum values, sample name, property values
- Property statistics
Useful for programmatic use (Python, R, custom scripts).
Download as Excel
An .xlsx file with two sheets:
| Sheet | Contents |
|---|
| Spectra | Long table: each row is a sample. Columns: sample name, property values, then one column per wavenumber/wavelength point with the intensity value. |
| Metadata | Key-value pairs describing the dataset (name, description, sensor info, units, range, sample count, feature count, creator, creation date). |
Both formats include the original raw spectra and property values. They do not include any model artifacts or predictions. Use them as a portable backup of the snapshot.
