📖 Overview

AutoMD-Viz is a standalone visualization toolkit for generating publication-quality figures from molecular dynamics simulation data. It supports multiple visualization types and journal-specific styles (Nature, Science, Cell).

Key Features:

• 🎨 Molecular structure visualization (PyMOL)
• 📊 Data plotting (Matplotlib/Seaborn)
• 🎬 Trajectory visualization (PCA/t-SNE/UMAP)
• 📦 Automated report generation
• 🎯 Journal-specific styles (Nature/Science/Cell)
• 🔧 High-resolution output (300-600 DPI, SVG/PDF/EPS)

🚀 Quick Start

Installation

bash

# Via ClawHub
clawhub install automd-viz

# Or manual installation
git clone https://github.com/Billwanttobetop/automd-viz.git
cd automd-viz
chmod +x automd-viz.sh

Basic Usage

bash

# Generate protein structure figure
./automd-viz.sh --type structure --structure protein.pdb --style nature

# Plot RMSD/RMSF data
./automd-viz.sh --type data --input rmsd.xvg --style science

# Trajectory visualization (PCA)
./automd-viz.sh --type trajectory --structure protein.pdb --trajectory md.xtc

# Generate complete report
./automd-viz.sh --type report --structure protein.pdb --trajectory md.xtc --style nature

📋 Visualization Types

1. Structure Visualization (--type structure)

Generate high-quality molecular structure figures using PyMOL.

Options:

• --structure <file> - Input structure (PDB/GRO)
• --style <nature|science|cell> - Journal style
• --representation <cartoon|surface|sticks> - Display style
• --color <spectrum|chain|secondary> - Coloring scheme
• --resolution <300|600> - Output DPI

Example:

bash

./automd-viz.sh --type structure \
  --structure protein.pdb \
  --style nature \
  --representation cartoon \
  --color spectrum \
  --resolution 600

Output:

• structure_nature.png (high-resolution raster)
• structure_nature.pse (PyMOL session)

---

2. Data Plotting (--type data)

Plot time-series data (RMSD, RMSF, energy, etc.) with journal-quality formatting.

Options:

• --input <file> - Input data file (XVG format)
• --style <nature|science|cell> - Journal style
• --xlabel <text> - X-axis label
• --ylabel <text> - Y-axis label
• --title <text> - Plot title

Example:

bash

./automd-viz.sh --type data \
  --input rmsd.xvg \
  --style science \
  --xlabel "Time (ns)" \
  --ylabel "RMSD (nm)"

Output:

• data_plot.pdf (vector graphics)
• data_plot.png (raster graphics)

---

3. Trajectory Visualization (--type trajectory)

Visualize trajectory in reduced dimensionality space (PCA/t-SNE/UMAP).

Options:

• --structure <file> - Reference structure
• --trajectory <file> - Trajectory file (XTC/TRR)
• --method <pca|tsne|umap> - Dimensionality reduction method
• --style <nature|science|cell> - Journal style

Example:

bash

./automd-viz.sh --type trajectory \
  --structure protein.pdb \
  --trajectory md.xtc \
  --method pca \
  --style nature

Output:

• trajectory_pca_2d.pdf (2D projection)
• trajectory_pca_3d.pdf (3D projection)
• free_energy_landscape.pdf (FEL)

---

4. Automated Report (--type report)

Generate a complete set of publication-ready figures.

Options:

• --structure <file> - Reference structure
• --trajectory <file> - Trajectory file
• --input <dir> - Analysis results directory
• --style <nature|science|cell> - Journal style

Example:

bash

./automd-viz.sh --type report \
  --structure protein.pdb \
  --trajectory md.xtc \
  --input analysis-results/ \
  --style nature

Output:

• figures/ directory with all figures
• VISUALIZATION_REPORT.md (summary)

---

🔧 Dependencies

Required:

• Python 3.7+
• NumPy
• Matplotlib
• Seaborn

Optional (for advanced features):

• PyMOL (structure visualization)
• scikit-learn (PCA/t-SNE)
• umap-learn (UMAP)
• MDAnalysis (trajectory processing)

Auto-install:

bash

pip install numpy matplotlib seaborn scikit-learn umap-learn MDAnalysis

📚 Integration with AutoMD-GROMACS

AutoMD-Viz is designed to work seamlessly with AutoMD-GROMACS analysis results.

After running analysis:

bash

# Run analysis
advanced-analysis -s md.tpr -f md.xtc

# Visualize results
automd-viz --type report --input advanced-analysis/ --style nature

Supported analysis outputs:

• RMSD/RMSF/Rg (from analysis.sh)
• PCA/Clustering (from advanced-analysis.sh)
• Binding analysis (from binding-analysis.sh)
• Trajectory analysis (from trajectory-analysis.sh)
• Property analysis (from property-analysis.sh)

---

🐛 Troubleshooting

See publication-viz-errors.md for common issues and solutions.

Quick fixes:

• PyMOL not found → Install PyMOL or use --no-structure
• Font issues → Install required fonts or use --font-fallback
• Memory errors → Reduce trajectory frames with --stride
