peak-o-mat is a data analysis and curve fitting program written in 100% Python. It is especially designed to fit spectroscopic data but should be suited for any other fitting task. It allows for clearing, transforming, fitting, calibrating, etc. of spectra with few mouse clicks. peak-o-mat can easily be extended by writing your own modules, it has been tested on windows, linux and OSX.
You need at least python 3.7 and the following packages:
All packages here above can be installed via pip, there is no need for any python package manager. Once all dependencies are installed,
download the zip file (https://github.com/kurisutsukato/peak-o-mat/archive/refs/heads/master.zip) and run peak-o-mat-py.
A big thank goes to Rubin Dunn. Without him devellopping and mainting wxPython for over 20 years now, peak-o-mat would not exist.
