Orange Workflows for s-SNOM

In this repository there is some examples about how to open and post-process files from neaSNOM microscope.

The experimental data used in these examples was courtesy of FERES (2021).

To download these examples click on:

• Code;
• Download the ZIP; - This will take a while, because it is a large file.
• Select the folder and extract;
• Open orange; - If you do not have orange spectroscopy installed, download Quasar or Orange.
• After running Orange, open the example;
  • File >> Open >> example
• Now you need to indicate the file, in this example we have the filename and the reference written at the top of the orange desktop;
• And follow the instructions...

In this equipament is possible to generate 3 main types of data, with a better descrition of this types in this respective folders.

• Point Spectrum:

  This is just a spectrum measured in just one position.

  This data has a full spectrum data, wavenumber approximately 600 cm^-1 up to 2000 cm^-1, but in only one pixel.

• Linescan:

  In this case, a full spectrum of each pixel along a path choose is during the experiment.

• Hyperspectral Image:

  In the last type is a full spectrum on each pixel inside an area.
