Fitting of time-of-flight mass spectra with Hyper-EMG models
* Free software: 3-clause BSD license
* Online documentation: https://RobbenRoll.github.io/emgfit.
* Source code: https://github.com/RobbenRoll/emgfit
`emgfit` is a Python package for peak fitting of time-of-flight (TOF) mass
spectra with hyper-exponentially modified Gaussian (Hyper-EMG_ [1]_) model
functions. `emgfit` is a wrapper around the `lmfit`_ [2]_ curve fitting package
and uses many of lmfit's user-friendly high-level features. Experience with
`lmfit` can be helpful but is not an essential prerequisite for using `emgfit`
since the `lmfit` features stay largely 'hidden under the hood'. `emgfit` is
designed to be user-friendly and offers automation features whenever reasonable
while also supporting a large amount of flexibility and control for the user.
Depending on the user's preferences an entire spectrum can be rapidly analyzed
with only a few lines of code. Alternatively, various optional features are
available to aid the user in a more rigorous analysis. The model functions and
statistical methods provided by emgfit could be useful for analyses of
spectroscopic data from a variety of other fields.
Amongst other features, the `emgfit` toolbox includes:
* Automatic and sensitive peak detection
* Automatic import of literature values from the AME2020_ [3]_ (or
AME2016_ [4]_) mass database
* Automatic selection of the best suited peak-shape model
* Fitting of low-statistics peaks with a binned maximum likelihood method
* Simultaneous fitting of an entire spectrum with various peaks
* Export of all relevant fit results including fit statistics and plots to an
EXCEL output file for convenient post-processing
`emgfit` is designed to be used within Jupyter Notebooks which have become a
standard tool in the data science community. The usage and capabilities of
`emgfit` are best explored by looking at the tutorial. The tutorial and more
details can be found in the `online documentation`_.
