• Python package for applied analytical chemistry focused primarily on mass speectrometry

Project in practical programming in chemistry course -- EPFL CH-200

Package description

MASSiveChem, which stands for "Mass Analytical Spectrometry System for Investigation and Visual Extrapolation in Chemistry", is a pip-installable package developped at EPFL in 2024 focused on, as its name would suggest, analytical chemistry. The aim of this package is to provide the user functions in order to simulate the mass spectrum of a molecule and to display this spectrum on a graph. The package also provides other features that can facilitate the chemical analysis of a molecule such as a functional group finder and an instauration calculator.

Developpers:

• Thomas Viking Christiansson, student in chemical engineering at EPFL https://github.com/ThomasCsson

What is mass spectrometry ?

• Mass spectrometry is an analytical technique used to identify and quantify chemical compounds in a sample by measuring the mass and sometimes the charge of molecules. It involves separating pre-charged ions according to their mass-to-charge ratio (m/z), then detecting and analysing them. This method is widely used in chemistry, biochemistry, pharmacology and other fields to characterise substances and understand their composition.

now, let us go through the steps required to use this package !

Installation

MASSiveChem can be installed using pip as

pip install MASSiveChem

The package can also be installed from source by running the following commands

First clone the repository from github

git clone https://github.com/ThomasCsson/ppchem-project-Christiansson-Gonteri-Humery.git
cd ThomasCsson/ppchem-project-Christiansson-Gonteri-Humery

Then, execute the shell script. The shell scripts require two arguments, python version and gpu/cpu.

source scripts/install_deepchem_conda.sh 3.10 cpu

Requirments

The package runs on python 3.10 but supports python 3.8 through 3.10 The package requires several other packages to function correctly.

matplotlib
bokeh
rdkit
pandas

If everything runs in order during the installation, the preceding packages should install automatically. But check that the following packages are correctly installed using

pip show "name of the package"

If not, install them using the following commands, otherwise the package will not work.

pip install matplotlib
pip install bokeh
pip install rdkit
pip install pandas
