Orange for spectral data

This is an add-on for Orange3 for the analysis of spectral data.


To use this add-on, first download and install the current version of Orange3. Next, install the add-on:

  1. Open Orange Canvas, choose "Options" from the menu and then "Add-ons".
  2. A new window will open. There, tick the checkbox in front of "Spectroscopy" and confirm.
  3. Restart Orange.


After the installation, the widgets from this add-on are registered with Orange. The new widgets will appear in Orange Canvas, in the toolbox bar under the section Spectroscopy.

For developers

If you would like to install from cloned git repository, run

pip install .

To register this add-on with Orange, but keep the code in the development directory (do not copy it to Python's site-packages directory), run

pip install -e .
