A research platform for spectral data

HARKANA

Processing, visualization, and collaboration for single spectra, spectral time-series, and hyperspectral datasets.

From individual spectra to multidimensional measurements

Single spectra

Process individual measurements and compare spectral signals with their analysis results.

Spectral time-series

Explore sequences of spectra and follow how spectral signals change over time.

Hyperspectral datasets

Connect spatial patterns with spectral signals through linked images and line charts.

Supported inputs

Text (TXT/ASC), CSV/TSV, JSON, SPC, TIFF/OME-TIFF, Olympus OIR, ENVI, NetCDF, Igor, and OME-Zarr folders.

Processing workflows

Define an analysis. Reuse it across datasets.

Connect processing steps into workflows that run in the cloud. Define the results to save and the visualizations to explore, then save and share workflows for future analyses.

Machine-readable documentation supports workflow design with large language models.

Visualization and exploration

Explore images and spectral signals together

Select a pixel or region to inspect its spectra. Compare measurements and results, choose visualizations, and arrange the viewer to suit your analysis.
