chromatopy 1.7.0

Peak integration software.

chromatoPy (1.7.0)

chromatoPy is an open-source Python package designed to streamline the integration and analysis of High-Performance Liquid Chromatography (HPLC) data. It features flexible multi-Gaussian and single Gaussian fitting algorithms to detect, fit, and integrate peaks from chromatographic data, enabling efficient analysis and processing of complex datasets. Note, interactive integration requires internal spike standard (Trace 744).

Features

• Flexible Gaussian Fitting: Supports both single and multi-Gaussian peak fitting algorithms. -- Fit Uncertainty: An ensemble peak areas are calculated using uncertainty in fitting parameters (peak width, height, and centre).
• Data Integration: Integrates chromatographic peak data for precise quantification.
• Customizable Analysis: Allows for the adjustment of fitting parameters to accommodate various peak shapes.
• Input Support: Works with HPLC data converted to .csv format using a built in function that utilizes the package "rainbow".

Installation

To install chromatoPy from the GitHub repository, you can use the following pip command:

pip install chromatopy

Requirements

• Python 3.12.4 or higher
• Dependencies are automatically installed when you install the package:
• numpy==1.26.4
• pandas==2.2.2
• scikit-learn==1.4.2
• scipy==1.13.1
• matplotlib==3.8.4
• rainbow-api==1.0.9
• pybaselines==1.1.0

Note on Development and Testing

This package has been developed and tested using the Spyder IDE. While it is expected to work in other development environments, it has not been specifically tested with other IDEs. If you encounter any issues when using the package in a different environment, please feel free to raise an issue or reach out for support.

Usage

Once installed, you can start using chromatoPy to analyze your HPLC chromatographic data. Below is a basic example demonstrating how to use the package to load and analyze data:

Example

import chromatopy

# Convert chromatography data to .csv files
chromatopy.hplc_to_csv()

# Run interactive analyzer
chromatopy.hplc_integration()

# Calculate and assign indices
chromatopy.assign_indices()

Input Data Requirements

chromatoPy expects HPLC data to be in .csv format. You can convert your raw HPLC results using the hplc_to_csv() function.

Versioning

Version numbers are reported in an "X.Y.Z" format.

• X (Major version): changes that would require the user to adapt their usage of the package (e.g., removing or renaming functions or methods, introducing new functions that change functionality).
• Y (Minor version): modifications to functions or new features that are backward-compatible.
• Z (Patch version): minor bug fixes or enhancements that do not affect the core interface/method.
