is the software to spectra analysis which present data in a graph way.

It is open-source, non-commercial, user friendly, the software is written in Python and kivy.

Spectrus offers a load file method, which grab two the column of data but without the trash (e.g. spectrum noise), automatically.

The Spectrus gives the ability to easy-to-use spectrum subtraction with define value, set to zero, as well as normalization the spectrum (Absorbance value, 0-1).

This program provides only a single spectra display on one time, but after adding the prepared spectra is possible to load the next spectra. After adding all spectra it is an easy way to save a prepared file.

pip3 install -r requirements.txt

You simply run command: python3 App.py from root directory

Choosing:

• "Load" button, and choose /docs/examples/84.dx

• you can change the range of spectra by changing range in label rangefrom: to: and use btn DRAW

• mouse position (x,y) is display in right upper corner. You can glance the value which you want substract with substract button

• default substract min button use very often use substrating to zero

• additionally, normalize substract to min and set maximum to 1.0

• if you don't want to save each spectra, use clear button or just load new spectra

• if you set up properly the spectra, click add button and you can use name of this spectra

• in the left panel you can observe which spectra you add, and also in right corner but only as a number

• if you process all needed data you can save it with save button. Please choose location and filename

python -m unittest tests/tests.py
