+# VAF vs Depth Plots - Implementation Summary
+
+## Overview
+
+This implementation adds comprehensive plotting functionality for analyzing the relationship between sequencing depth and various quantitative metrics in the deepCSA pipeline, as requested in the issue.
+
+## Issue Requirements
+
+The original issue requested plots for:
+- ✅ VAF (depth per site)
+- ✅ Mutation density (with depth value from mutation density file & average depth per gene)
+  - ✅ Different flavors: all, protein affecting, non-protein affecting
+- ✅ Omega (average depth per gene)
+- ✅ OncodriveFML (average depth per gene)
+
+All requirements have been fully implemented.
+
+## Implementation Details
+
+### 1. Main Plotting Script: `bin/plot_vaf_depth.py`
+
+**Purpose**: Generate scatter plots showing depth-metric relationships with hyperbolic curves
+
+**Key Functions**:
+- `add_hyperbolic_curves()`: Adds N/depth curves to plots
+- `count_mutations_on_curves()`: Counts mutations following each hyperbolic curve
+- `plot_vaf_vs_depth_per_site()`: VAF scatter plot with per-site depth
+- `plot_mutdensity_vs_depth()`: Mutation density plots per gene
+- `plot_omega_vs_depth()`: dN/dS ratio plots per gene
+- `plot_oncodrivefml_vs_depth()`: OncodriveFML score plots per gene
+
+**Features**:
+- Hyperbolic curves: N/depth for N=1,2,3...configurable (default: 10)
+- Automatic mutation counting with configurable tolerance (default: 5%)
+- Support for multiple mutation type flavors
+- Color-coding by statistical significance
+- Comprehensive data validation and filtering
+
+### 2. Nextflow Module: `modules/local/plot/vaf_depth/`
+
+**Structure**:
+```
+modules/local/plot/vaf_depth/
+├── main.nf      # Process definition
+└── meta.yml     # Module metadata
+```
+
+**Process Features**:
+- Flexible input handling (all files optional except sample name)
+- Uses existing deepCSA container
+- Configurable parameters via task.ext
+- Version tracking
+- Stub implementation for testing
+
+**Input Channels**:
+- `tuple val(meta), path(maf), path(mutdensity), path(omega), path(oncodrivefml)`
+- `tuple val(meta2), path(depth)`
+
+**Output**:
+- PDF file with all generated plots
+- versions.yml for reproducibility
+
+### 3. Documentation: `docs/vaf_depth_plots.md`
+
+Comprehensive guide covering:
+- Feature overview and use cases
+- Detailed explanation of hyperbolic curves
+- Input file specifications
+- Output interpretation guidelines
+- Command-line usage examples
+- Nextflow integration examples
+
+### 4. Example Script: `docs/examples/vaf_depth_plots_example.sh`
+
+Demonstrates three usage patterns:
+1. VAF-only plotting (MAF file only)
+2. Mutation density plotting (mutation density + depth)
+3. Complete analysis (all metrics together)
+
+## Technical Approach
+
+### Hyperbolic Curves
+
+The implementation adds curves representing `VAF = N / depth` where N is the number of mutant reads:
+
+```python
+for n in range(1, max_n + 1):
+    vaf_curve = n / depth_range
+    # Plot only if VAF <= 1.0
+    if valid_mask.sum() > 0:
+        ax.plot(depth_range[valid_mask], vaf_curve[valid_mask], ...)
+```
+
+This helps identify:
+- Low-frequency mutations (N=1,2,3)
+- Technical artifacts vs biological signals
+- Sequencing depth effects on detection
+
+### Mutation Counting Algorithm
+
+Mutations are assigned to curves using relative tolerance:
+
+```python
+expected_vaf = n / depth
+relative_diff = abs(vaf - expected_vaf) / (expected_vaf + epsilon)
+on_curve = (relative_diff <= tolerance) & (expected_vaf <= 1.0)
+```
+
+- Default tolerance: 5% relative difference
+- Prevents double-counting (mutations assigned to first matching curve)
+- Counts remaining mutations as "other"
+
+### Mutation Density Adaptation
+
+For gene-level metrics, reference curves show expected densities:
+
+```python
+density_curve = (n_muts / depth_range) * 1e6
+```
+
+This represents the mutation density (per Mb) for N mutations at various average gene depths.
+
+## Integration with deepCSA
+
+### Data Flow
+
+```
+VCF/BAM → vcf2maf → MAF file
+                       ↓
+                    plot_vaf_depth.py → VAF plots
+                       
+mutations + panel → compute_mutdensity → mutation density file
+                                              ↓
+                                    plot_vaf_depth.py → density plots
+                                    
+mutations → dndscv → omega file
+                        ↓
+              plot_vaf_depth.py → omega plots
+              
+mutations → oncodrivefml → oncodrivefml file
+                              ↓
+                    plot_vaf_depth.py → ofml plots
+
+BAM + panel → plot_depths → depth_per_gene file
+                                ↓
+                        (required for gene-level plots)
+```
+
+### Existing Code Integration
+
+The implementation follows deepCSA conventions:
+- Uses `read_utils.custom_na_values` for consistent NA handling
+- Uses `utils_plot.plots_general_config` for styling
+- Follows existing plot script patterns (click CLI, PdfPages output)
+- Compatible with existing Docker container
+
+## Testing and Validation
+
+### Validation Performed
+
+1. ✅ **Syntax Validation**: Python AST parsing confirms valid syntax
+2. ✅ **Structure Validation**: All required functions implemented
+3. ✅ **Module Validation**: Nextflow process structure verified
+4. ✅ **Security Scan**: CodeQL found no vulnerabilities
+5. ✅ **File Permissions**: Scripts are executable
+
+### Manual Testing Approach
+
+Due to lack of dependencies in the local environment, testing requires:
+
+1. Running within the deepCSA Docker container:
+   ```bash
+   singularity exec docker://bbglab/deepcsa-core:0.0.2-alpha bash
+   ```
+
+2. Using real pipeline outputs as test data
+
+3. Visual inspection of generated PDF plots
+
+## Code Quality
+
+### Metrics
+- Total new code: ~27 KB across 5 files
+- Python code: 424 lines (bin/plot_vaf_depth.py)
+- Nextflow code: 55 lines (main.nf)
+- Documentation: 206 + 44 lines (markdown + examples)
+- Comments and docstrings: Comprehensive throughout
+
+### Design Principles
+- **Modularity**: Each plot type in separate function
+- **Reusability**: Utility functions for curves and counting
+- **Flexibility**: All inputs optional, graceful handling of missing data
+- **Consistency**: Follows deepCSA styling and patterns
+- **Robustness**: Input validation, error handling, edge case management
+
+## Future Enhancements
+
+Potential improvements for future work:
+
+1. **Interactive plots**: Add HTML output option with plotly
+2. **Statistical tests**: Formal tests for deviations from expected curves
+3. **Batch processing**: Support multiple samples in single run

+# VAF and Selection Metrics vs Depth Plots
+
+## Overview
+
+The depth relationship plotting modules generate scatter plots showing the relationship between sequencing depth and various quantitative metrics. These plots help identify patterns in mutation data and assess whether mutations follow expected depth-dependent patterns.
+
+## Features
+
+The implementation consists of two independent modules:
+
+### Module 1: VAF and Mutation Density (with hyperbolic curves)
+
+1. **VAF (Variant Allele Frequency) vs Depth per Site**
+   - Scatter plot of individual mutations
+   - Overlay of hyperbolic curves (N/depth for N=1,2,3...)
+   - Counts of mutations following each curve
+
+2. **Mutation Density vs Average Depth per Gene**
+   - Separate plots for different mutation types:
+     - All mutations
+     - SNV only
+     - Insertions/Deletions
+     - Protein-affecting vs non-protein-affecting
+   - Reference curves showing expected densities
+
+### Module 2: Selection Metrics (without hyperbolic curves)
+
+3. **Omega (dN/dS) vs Average Depth per Gene**
+   - Color-coded by statistical significance (p < 0.05)
+   - Separate plots for missense and truncating mutations
+   - Reference line at neutral selection (ω=1)
+   - **No hyperbolic curves**
+
+4. **OncodriveFML Score vs Average Depth per Gene**
+   - Color-coded by q-value significance
+   - Identifies genes with functional bias
+   - **No hyperbolic curves**
+
+## Hyperbolic Curves
+
+The hyperbolic curves represent the expected VAF for N mutant reads at various depths:
+
+```
+VAF = N / depth
+```
+
+Where:
+- N = number of mutant reads (1, 2, 3, ...)
+- depth = total sequencing depth at that position
+
+These curves help identify:
+- Low-frequency mutations (N=1,2,3)
+- Technical artifacts vs true biological signals
+- Sequencing depth effects on variant detection
+
+## Usage
+
+### Command Line
+
+**For VAF and Mutation Density (with hyperbolic curves):**
+```bash
+plot_vaf_mutdensity_depth.py \
+  --sample_name SAMPLE_ID \
+  --maf_file mutations.maf \
+  --mutdensity_file mutdensity.tsv \
+  --depth_file depth_per_gene.tsv \
+  --output_prefix output_name \
+  --max_n 10
+```
+
+**For Selection Metrics (without hyperbolic curves):**
+```bash
+plot_selection_depth.py \
+  --sample_name SAMPLE_ID \
+  --omega_file omega_results.tsv \
+  --oncodrivefml_file oncodrivefml_results.tsv \
+  --depth_file depth_per_gene.tsv \
+  --output_prefix output_name
+```
+
+### In Nextflow Pipeline
+
+The modules are integrated via the `PLOT_DEPTH_RELATIONSHIPS` subworkflow. Enable with:
+
+```yaml
+# In nextflow.config or params file
+plot_depth_relationships = true
+```
+
+The workflow automatically runs the appropriate modules based on available data:
+- Runs VAF/mutation density module if MAF or mutation density files exist
+- Runs selection metrics module if omega or OncodriveFML results exist
+- Each module operates independently
+
+## Input Files

+- `CHROM`: Chromosome
+- `POS`: Position
+- `DEPTH`: Total sequencing depth
+- `VAF`: Variant allele frequency (0-1)
+- `ALT_DEPTH`: Number of reads supporting alternate allele
+- `GENE`: Gene name
+
+### Mutation Density File (Required for density plots)
+Tab-separated file with columns:
+- `SAMPLE_ID`: Sample identifier
+- `GENE`: Gene name
+- `MUTTYPES`: Type of mutations (e.g., 'all_types', 'SNV', 'DELETION')

+- `dnds`: dN/dS ratio (omega)
+- `pvalue`: Statistical significance
+- `mutations`: Number of mutations
+
+### OncodriveFML File (Optional)
+Tab-separated file with columns:
+- `SYMBOL`: Gene symbol
+- `SCORE`: OncodriveFML score
+- `PVALUE`: P-value
+- `QVALUE`: FDR-corrected q-value
+
+## Output
+
+A single PDF file containing all generated plots:
+- `{output_prefix}.vaf_depth_plots.pdf`
+
+Each plot includes:
+- Scatter points for data
+- Hyperbolic curves (for VAF plots)
+- Reference lines (for selection plots)
+- Annotation boxes with counts and statistics
+- Proper axis labels and titles
+
+## Interpretation
+
+### VAF vs Depth Plots
+
+**Mutations on low N curves (N=1,2,3)**
+- May represent rare variants or technical artifacts
+- Higher sequencing depth improves detection
+
+**Mutations deviating from curves**
+- Could indicate:
+  - Copy number alterations
+  - Subclonal populations
+  - Technical issues with depth calculation
+
+### Mutation Density Plots
+
+**High density at low depth**
+- May indicate:
+  - Poor sequencing quality in specific genes
+  - Regions prone to sequencing errors
+
+**Consistent density across depths**
+- Suggests uniform mutation processes
+
+### Selection Plots (Omega)
+
+**ω > 1** (red points if p < 0.05)
+- Positive selection
+- More non-synonymous than expected
+
+**ω < 1**
+- Purifying selection
+- Fewer non-synonymous than expected
+
+**ω ≈ 1**
+- Neutral evolution
+
+## Parameters
+
+- `--sample_name`: Sample identifier (required)
+- `--maf_file`: Path to MAF file (optional)
+- `--mutdensity_file`: Path to mutation density file (optional)
+- `--depth_file`: Path to depth per gene file (optional)
+- `--omega_file`: Path to omega results (optional)
+- `--oncodrivefml_file`: Path to OncodriveFML results (optional)
+- `--output_prefix`: Output file prefix (required)
+- `--max_n`: Maximum N for hyperbolic curves (default: 10)
+
+## Example
+
+**For VAF and mutation density analysis:**
+```bash
+plot_vaf_mutdensity_depth.py \
+  --sample_name bladder_sample_01 \
+  --maf_file results/bladder_sample_01.maf \
+  --mutdensity_file results/bladder_sample_01.mutdensities.tsv \
+  --depth_file results/bladder_sample_01.depth_per_gene.tsv \
+  --output_prefix bladder_sample_01 \
+  --max_n 15
+```
+Creates: `bladder_sample_01.vaf_mutdensity_depth.pdf`
+
+**For selection metrics analysis:**
+```bash
+plot_selection_depth.py \
+  --sample_name bladder_sample_01 \
+  --omega_file results/bladder_sample_01.omega.tsv \
+  --oncodrivefml_file results/bladder_sample_01.oncodrivefml.tsv \
+  --depth_file results/bladder_sample_01.depth_per_gene.tsv \
+  --output_prefix bladder_sample_01
+```
+Creates: `bladder_sample_01.selection_depth.pdf`
+
+## Notes
+
+- The modules are independent and can run separately
+- **VAF/mutation density module**: At least MAF or mutation density file required; generates plots with hyperbolic curves
+- **Selection metrics module**: At least omega or OncodriveFML file required; generates plots WITHOUT hyperbolic curves
+- Depth per gene file is required for mutation density, omega, and OncodriveFML plots
+- All plots use consistent styling from `utils_plot.py`
+- Hyperbolic curves appear only on VAF and mutation density plots, not on selection metrics plots
