GMXvg 1.0.1

A tool to plot GROMACS .xvg files.

🧬 GMXvg: GROMACS .xvg File Plotting Tool

Transform your GROMACS simulation data into publication-ready plots

GMXvg is a command-line utility designed for converting and plotting GROMACS XVG files. It simplifies the process of handling XVG files by automatically discovering all XVG files in the current or subdirectories and converting them to specified file formats, with JPG as the default format. Additionally, GMXvg logs the summary of plots in a CSV file, providing quick access to plot values along with their standard deviation.

🌟 Features

• Automatic discovery - Finds all .xvg files in directories
• Multiple formats - Export to JPG, PNG, PDF, SVG, and more
• Batch processing - Analyze hundreds of files at once
• Statistical summaries - Automatic calculation of means and standard deviations
• Customizable - Full control over plot appearance and output quality
• Cross-platform - Can be installed and used on Windows, MacOS, and Linux

🚀 Quick Start (3 Easy Steps!)

Step 1: Install

pip install gmxvg

Step 2: Check it works

gmxvg --version

Step 3: Create your first plot

# If you have .xvg files in your current folder:
gmxvg

# Or specify a folder:
gmxvg -b /path/to/your/xvg/files

That's it! 🎉 Your plots will be created automatically.

📊 What Can You Analyze?

GMXvg works with all standard GROMACS output files including:

File Type	Description
RMSD	Root Mean Square Deviation - structural stability
RMSF	Root Mean Square Fluctuation - flexibility analysis
Energy	Potential, kinetic, and total energy plots
Temperature	System temperature monitoring
Pressure	System pressure analysis
Hydrogen Bonds	Molecular interaction analysis

💡 Examples

Basic Usage

# Plot all .xvg files in current directory
gmxvg

# Plot files in a specific directory
gmxvg -b /path/to/simulation/results

# Create high-resolution plots for publication
gmxvg -d 600 -e png pdf

# Plot multiple directories at once
gmxvg -md /path/to/folder1 /path/to/folder2 /path/to/folder3

🏥 Troubleshooting

Common Issues

"No .xvg files found"

• Make sure you're in the right directory
• Check if files have the .xvg extension
• Use -b to specify the correct path or start terminal from the directory containing your graphs

"Import error"

• Try: pip install --upgrade gmxvg
• Make sure you have Python 3.6+

"Plots look strange"

• Check if your .xvg files are properly formatted
