PyHRMS: Tools For working with High Resolution Mass Spectrometry (HRMS) data in Environmental Science

PyHRMS is a python package for processing high resolution Mass Spectrometry data coupled with gas chromatogram (GC) or liquid chromatogram (LC).

It aims to provide user friendly tool to read, process and visualize LC/GC-HRMS data for scientist.

First release date: Nov.15.2021

Jan.15.2023: pyhrms 0.5.01 new features:

optimize algorithm

add function to process SWATH data

Installation & major dependencies pyhrms can be installed and import as following:

` pip install pyhrms `

If you just want to update a new version, please update as following:

` pip install pyhrms -U `

PyHRMS provides following functions:

Read raw LC/GC-HRMS data in mzML format;
Powerful and accurate peak picking function for LC/GC HRMS;
retention time (rt) and mass over Z stands for charge number of ions (m/z) will be aligned based on user defined error range.
Accurate function for comparing response between/among two or more samples;
Covert profile data to centroid
Parallel computing to improve efficiency;
Interactive visualizations of raw mzML data;
Supporting searching for Local database and massbank;
MS quality evaluation for ms data in profile.
Can process SWATH data.
