+# ALICE O2Physics PID Feature Extractor
+
+A comprehensive C++ task for the O2Physics framework that extracts particle identification (PID) features from ALICE AO2D files. This tool processes track data and generates high-quality features suitable for machine learning-based particle identification.
+
+## Overview
+
+The **PIDFeatureExtractor** combines information from multiple ALICE detectors (TPC and TOF) to create a rich feature set for distinguishing between different particle types (pions, kaons, protons, and electrons). The extracted features are saved in both ROOT TTree and CSV formats for easy access and analysis.
+
+### Key Features
+
+- **Multi-Detector Integration**: Combines TPC (dE/dx) and TOF (time-of-flight) PID information
+- **CCDB Integration**: Automatically fetches unavailable features from the ALICE Conditions Database (CCDB)
+- **Bayesian Probability Computation**: Calculates combined PID probabilities using Gaussian likelihood in n-sigma space
+- **Flexible Output**: Exports to both ROOT TTree and CSV formats simultaneously
+- **Quality Control**: Includes QC histograms for track kinematics and detector response
+- **MC Truth Matching**: Includes Monte Carlo truth information for simulated data
+- **Configurable Selection**: User-adjustable kinematic cuts (pT, η range) via JSON configuration
+- **Track Quality Metrics**: Stores DCA and TPC fit quality information
+
+## Requirements
+
+### O2Physics Environment
+
+- **O2Physics framework**: Latest version with PID response tables and CCDB access
+- **ROOT**: Version 6.x or later
+- **CMake**: 3.x or later
+- **C++ Standard**: C++17 or later
+- **CCDB Access**: Network connection to ALICE CCDB for fetching PID calibrations
+- **bash**: For running the `run.sh` execution script
+
+### Required Data Tables
+
+The task expects the following input tables from AO2D files. Some tables may be fetched from CCDB if not present in the file:
+
+| Table                    | Source    | Purpose                                          | Fallback |
+|--------------------------|-----------|--------------------------------------------------|----------|

+
+## Data Flow and CCDB Integration
+
+### Processing Pipeline
+
+```
+AO2D File
+    ↓
+Load Configuration from myConfigExtractor.json
+    ↓
+Initialize O2Physics Workflow
+    ↓
+Load Tracks + Available PID Tables
+    ↓
+Missing Features? → Query CCDB (using timestamp)
+    ↓
+Compute Bayesian PID (using AO2D or CCDB n-sigma values)
+    ↓
+Apply Track Selection (eta, pT cuts from config)
+    ↓
+Fill QC Histograms
+    ↓
+Write to ROOT TTree + CSV (based on config)
+```
+
+### CCDB Timestamp-Based Access
+
+The task uses the collision timestamp from each event to query CCDB for the correct calibration period:
+
+1. **Event Timestamp**: Read from collision data
+2. **CCDB Query**: Fetch PID calibrations valid for that timestamp
+3. **Feature Computation**: Use CCDB calibrations if AO2D values unavailable
+4. **Caching**: Calibrations are cached per run to minimize CCDB queries
+
+### Calibration Objects Retrieved from CCDB
+
+If not in AO2D, the task fetches:
+
+- **TPC PID Response**: Bethe-Bloch curve parameters and n-sigma calculation
+- **TOF PID Response**: TOF expected times and mass resolution
+- **Track Propagation**: Path length and TOF time calibrations
+- **Detector Resolution**: TPC and TOF resolution parameters for n-sigma computation
+
+## Output Files
+
+### ROOT Output (`<outputPath>.root`)
+
+Contains a TTree named `pid_features` with one entry per track. The tree includes all 39 features as separate branches. All feature values are either from AO2D or computed using CCDB calibrations.
+
+**Access in ROOT:**
+
+```cpp
+TFile file("pid_features.root");
+TTree* tree = (TTree*)file.Get("pid_features");
+
+// Plot TPC dE/dx vs pT (TPC signal always from AO2D)
+tree->Draw("tpc_signal:pt", "has_tpc==1", "scatter");
+
+// Select pions with high confidence (probabilities computed from CCDB if needed)
+tree->Draw("eta", "bayes_prob_pi > 0.9", "hist");
+```
+
+### CSV Output (`<outputPath>.csv`)
+
+Plain text comma-separated values format with header row. All 39 features are included. Features are either from AO2D or computed using CCDB calibrations. The filename is determined by the `output_path` parameter in `myConfigExtractor.json`.
+
+**Example CSV structure:**
+
+```csv
+event_id,track_id,px,py,pz,pt,p,eta,phi,theta,charge,track_type,...
+0,0,1.234,-0.567,2.345,1.456,2.678,-0.123,1.456,2.345,1,0,...
+0,1,0.987,0.654,1.234,1.123,1.567,0.456,2.123,0.987,-1,0,...
+```
+
+### Quality Control Histograms
+
+The task also produces QC histograms in the ROOT file:
+
+- `QC/nTracks`: Total number of processed tracks
+- `QC/pt`: pT distribution
+- `QC/eta`: Pseudorapidity distribution
+- `QC/tpc_dEdx_vs_pt`: TPC dE/dx vs pT (2D)
+- `QC/tof_beta_vs_p`: TOF beta vs momentum (2D)
+- `QC/mass_vs_p`: TOF mass vs momentum (2D)
+
+## Machine Learning Integration
+
+### Data Loading in Python
+
+```python
+import pandas as pd
+import numpy as np
+from sklearn.preprocessing import StandardScaler
+import xgboost as xgb
+
+# Load CSV file (features are from AO2D or CCDB-derived)
+# Output filename based on output_path from myConfigExtractor.json
+df = pd.read_csv("pid_features.csv")
+
+# Filter out invalid data (missing detector info)
+df_valid = df[(df['has_tpc'] == True) & (df['has_tof'] == True)]
+
+# Prepare features (exclude MC truth for real data)
+feature_cols = [col for col in df.columns
+                if col not in ['event_id', 'track_id', 'mc_pdg', 'mc_px', 'mc_py', 'mc_pz']]
+
+X = df_valid[feature_cols].values
+y = df_valid['mc_pdg'].values  # For simulated data
+
+# Standardize features
+scaler = StandardScaler()
+X_scaled = scaler.fit_transform(X)
+
+# Train model
+model = xgb.XGBClassifier(n_estimators=100, max_depth=6)
+model.fit(X_scaled, y)
+```
+
+### Loading ROOT File in Python
+
+```python
+import uproot
+import pandas as pd
+
+# Open ROOT file (output filename based on output_path from config)
+file = uproot.open("pid_features.root")
+tree = file["pid_features"]
+
+# Convert to pandas DataFrame
+df = tree.arrays(library="pd")
+
+# Access specific branches
+bayes_probs = df[['bayes_prob_pi', 'bayes_prob_ka', 'bayes_prob_pr', 'bayes_prob_el']]
+```
+
+## Algorithm Details
+
+### Bayesian PID Calculation
+
+The task computes Bayesian probabilities combining TPC and TOF information. n-sigma values are either from AO2D or computed using CCDB calibrations:
+
+**Likelihood Calculation:**
+
+For each particle hypothesis (π, K, p, e):
+
+```
+L_i = exp(-0.5 * (ns_TPC_i² + ns_TOF_i²))
+```
+
+Where `ns_TPC_i` and `ns_TOF_i` are n-sigma deviations from expected values (from AO2D or CCDB).
+
+**Prior Probabilities:**
+
+Default priors (configurable in source code):
+- Pions: 1.0
+- Kaons: 0.2
+- Protons: 0.1
+- Electrons: 0.05
+
+**Final Probabilities:**
+
+```
+P(i|TPC,TOF) = (L_i * Prior_i) / Σ(L_j * Prior_j)
+```
+
+This ensures the four probabilities sum to exactly 1.0.
+
+### Kinematic Calculations
+
+- **Transverse momentum**: \(p_T = \sqrt{p_x^2 + p_y^2}\)
+- **Total momentum**: \(p = \sqrt{p_x^2 + p_y^2 + p_z^2}\)
+- **Pseudorapidity**: \(\eta = -\ln(\tan(\theta/2))\)
+- **Polar angle**: \(\theta = 2 \arctan(e^{-\eta})\)
+
+### Invalid Data Handling
+
+- Missing TPC: All TPC variables set to `-999`
+- Missing TOF: All TOF variables set to `-999`
+- Missing CCDB connection: Task logs warning and uses available AO2D values
+- No MC match: `mc_pdg` set to `0`, momentum components set to `0`
+- Invalid TOF n-sigma (NaN): Treated as 0 contribution in Bayesian calculation
+
+## Troubleshooting
+
+### Issue: `./run.sh: command not found` or permission denied
+
+**Causes:**
+- Script is not executable
+- Running from wrong directory
+- Shell incompatibility
+
+**Solution:**
+
+```bash
+# Make executable
+chmod +x run.sh
+
+# Run explicitly with bash
+bash ./run.sh
+
+# Or run from correct directory
+cd ~/pid-extractor
+./run.sh
+```
+
+### Issue: Configuration file not found
+
+**Error Message:** `myConfigExtractor.json not found`
+
+**Causes:**
+- File doesn't exist in current directory
+- Running from wrong location
+
+**Solution:**
+
+```bash
+# Verify file exists
+ls -la myConfigExtractor.json
+
+# Ensure you're in the correct directory
+cd ~/pid-extractor
+./run.sh
+```
+
+### Issue: CCDB Connection Error
+
+**Error Message:** `Cannot connect to CCDB at <url>`
+
+**Causes:**
+- Network connectivity issues
+- CCDB server down
+- Incorrect CCDB URL in configuration
+
+**Solution:**
+
+1. Verify CCDB connectivity:
+```bash
+curl http://alice-ccdb.cern.ch/
+```
+
+2. Update `myConfigExtractor.json` with alternative CCDB:
+```json
+{
+  "ccdb_url": "http://alice-ccdb-test.cern.ch"
+}
+```
+
+3. Run again:
+```bash
+./run.sh
+```
+
+### Issue: Invalid JSON configuration
+
+**Error Message:** `JSON parse error` or similar
+
+**Causes:**
+- Syntax error in `myConfigExtractor.json`
+- Missing quotes or commas
+- Invalid data types
+
+**Solution:**
+
+1. Validate JSON syntax:
+```bash
+python3 -m json.tool myConfigExtractor.json
+```
+
+2. Fix any reported errors and retry:
+```bash
+./run.sh
+```
+
+### Issue: Features appear as -999 or invalid
+
+**Cause:** PID tables not in AO2D and CCDB fetch failed
+
+**Solution:**
+- Check network/CCDB access
+- Verify collision timestamp is within valid range
+- Ensure AO2D file contains basic track information
+
+### Issue: No tracks extracted
+
+**Causes:**
+- Track selection cuts too restrictive (check `eta_min`, `eta_max`, `pt_min`, `pt_max` in config)
+- Input data doesn't contain required track tables
+
+**Solution:**
+
+Edit `myConfigExtractor.json` to relax selection criteria:
+
+```json
+{
+  "eta_min": -1.5,
+  "eta_max": 1.5,
+  "pt_min": 0.1,
+  "pt_max": 20.0
+}
+```
+
+Then run:
+```bash
+./run.sh
+```
+
+### Issue: Many -999 values in TPC/TOF output
+
+**Cause:** Tracks lack TPC or TOF information (detector not active for those tracks)
+
+**Solution:**
+- Use track selection filters to require both detectors:
+```python
+df_valid = df[(df['has_tpc'] == True) & (df['has_tof'] == True)]
+```
+
+### Issue: CSV file is very large
+
+**Cause:** Processing too many tracks or both output formats enabled
+
+**Solutions:**
+
+Modify `myConfigExtractor.json`:
+
+```json
+{
+  "export_csv": false,
+  "export_root": true
+}
+```
+
+Or apply stricter cuts:
+
+```json
+{
+  "pt_min": 2.0,
+  "pt_max": 10.0,
+  "eta_min": -0.8,
+  "eta_max": 0.8
+}
+```
+
+Then run:
+```bash
+./run.sh
+```
+
+### Issue: ROOT TTree has no entries
+
+**Cause:** Track selection filtered out all tracks
+
+**Solution:**
+- Verify input data quality
+- Reduce selection criteria in `myConfigExtractor.json`
+- Check that tracks pass kinematic cuts
+- Verify CCDB calibrations loaded successfully
+
+## Performance Notes
+
+- **Processing Speed**: ~10,000 tracks/second (depends on system and CCDB latency)
+- **Memory Usage**: ~500 MB for typical dataset
+- **File Size**: ~50-100 bytes per track in CSV format
+- **CCDB Overhead**: Minimal after initial calibration load per run (~1-2 seconds)
+
+### Optimisation Tips
+
+1. **Use ROOT format for large datasets** (set `export_csv: false` in config)
+2. **Process in batches** for better memory management
+3. **Apply kinematic cuts** in `myConfigExtractor.json` to reduce output size
+4. **Disable MC truth** for real data to save space
+5. **Reuse CCDB connections** when processing multiple files from same run
+
+## Contributing
+
+### Adding New Features
+
+To add a new feature:
+
+1. Declare member variable in the struct
+2. Create TTree branch in `init()`
+3. Add CSV header column
+4. Fill variable in `process()`
+5. Update documentation
+
+Example:
+
+```cpp
+// 1. Member variable
+float my_new_feature;
+
+// 2. In init()
+featureTree->Branch("my_new_feature", &my_new_feature);
+
+// 3. In process()
+my_new_feature = t.someNewMethod();
+
+// 4. Update CSV
+csvFile << my_new_feature << ",";
+```
+
+### Modifying Configuration Options
+
+To add a new configurable parameter:
+
+1. Add parameter to `myConfigExtractor.json`
+2. Create `Configurable<T>` variable in task struct
+3. Use parameter value in processing logic
+4. Document in this README
+
+### Modifying Bayesian Priors
+
+Edit the priors array in the `process()` function of the task:
+
+```cpp
+float priors[4] = {1.f, 0.2f, 0.1f, 0.05f};  // π, K, p, e
+```
+
+### Fetching Additional CCDB Objects
+
+If you need additional calibrations:
+
+1. Query CCDB for the object path
+2. Load in the `init()` function using ccdbApi
+3. Cache calibration data for the processing period
+4. Use in `process()` function for feature computation
