Fields

FieldRequiredNotes
NameYesDescriptive label, e.g., “NIR Wheat Q1 2026”. Max 200 characters.
SensorYesOnly one sensor per dataset. Spectra from other sensors are not included.
DescriptionNoFree-text. Useful for noting filters applied, sample selection criteria, or data cleaning steps.

What gets included

When you create a dataset, the following are automatically included:
  • All active spectra for the chosen sensor (archived spectra are excluded)
  • The samples linked to those spectra
  • All sample properties defined in the project, with their values per sample
You don’t manually pick samples or properties. The dataset takes everything currently active for the sensor. To exclude specific spectra, archive them on the Spectra page before creating the dataset.
Curate before creating. A dataset is a frozen snapshot, so if you spot bad spectra after creating it, you’ll need to archive them and create a new version. Spend a few minutes on the Spectra page archiving outliers and known errors before clicking create.

Click create

Click Create Dataset. The button shows “Creating…” while the snapshot is being built. This usually takes a few seconds. You’re redirected to the dataset’s detail page where you can inspect everything that was captured.

Errors

The selected sensor has no spectra linked to it (or all of its spectra are archived). Upload spectra to that sensor first, or pick a different sensor.
Your plan limits how many datasets you can have per project. Archive or delete a dataset you no longer need, or upgrade your plan.
The Name field cannot be empty. Enter a descriptive name.
The Sensor field is required. Pick the sensor whose spectra you want in this dataset.

After creation

The dataset is now immutable. From its detail page you can:
  • Inspect the spectra, samples, properties, and sensor metadata
  • Download the dataset as JSON or Excel
  • Use it as input for an experiment
  • Create a new version when your data evolves
