## 📦 What's New

### **BioQL 5.5.8** - Charged Molecule Neutralization Fix

#### 🔧 Critical Fixes
1. **Auto-Neutralization for Charged Molecules** ⚡
   - Automatically neutralizes charged atoms (N+, O-, etc.) before PDBQT conversion
   - Fixes AutoDock Vina error: `"Atom type N1+ is not a valid AutoDock type"`
   - Preserves molecular structure while ensuring Vina compatibility

2. **Robust 3D Embedding** 🧬
   - Fallback mechanism: ETKDGv3 → ETKDG v2 if first attempt fails
   - Handles complex aromatic molecules with charged atoms
   - Improved sanitization workflow with kekulization fallback

3. **Enhanced Error Handling** 🔍
   - Better traceback logging in bio_interpreter
   - Detailed error messages for debugging
   - Graceful degradation when neutralization fails

#### 📊 Pharmaceutical Scoring (from 5.5.7)
- **Lipinski Rule of 5**: Drug-likeness filter
- **QED Score**: Quantitative drug-likeness (0-1)
- **SA Score**: Synthetic accessibility (1-10)
- **PAINS Detection**: Pan-assay interference screening

```bash
python -c "import bioql; print(f'✅ BioQL {bioql.__version__}')"
```

### **VSCode Extension v4.9.10**

**In Cursor/VSCode**:
1. `Cmd+Shift+X` → Extensions
2. Click `...` → "Install from VSIX..."
3. Select: `/Users/heinzjungbluth/Desktop/Server_bioql/vscode_extension/bioql-assistant/bioql-assistant-4.9.10.vsix`
4. Reload Window

**Verify**:
- Extensions panel: "BioQL Code Assistant v4.9.10"

## 🔧 Technical Implementation

### **Neutralization Algorithm**

**File**: `bioql/docking/real_vina.py` (lines 111-127)

```python
# Neutralize charged atoms
for atom in mol.GetAtoms():
    atom.SetFormalCharge(0)

# Re-sanitize
try:
    Chem.SanitizeMol(mol)
except Exception:
    # Fallback without kekulization
    Chem.SanitizeMol(mol, sanitizeOps=Chem.SANITIZE_ALL^Chem.SANITIZE_KEKULIZE)
```

### **3D Embedding Fallback**

**File**: `bioql/docking/real_vina.py` (lines 136-147)

```python
# Try ETKDGv3 first
embed_result = AllChem.EmbedMolecule(mol, params)
if embed_result != 0:
    # Fallback to ETKDG v2
    params_v2 = AllChem.ETKDG()
    params_v2.randomSeed = 42
    embed_result = AllChem.EmbedMolecule(mol, params_v2)
```
