+### Data loading Example
+**File**: `examples/load_example.ipynb`
+
+This notebook demonstrates all the data loading functions available in the ethopy_analysis package including:
+
+- **Configuration and Setup Functions**: Load configuration and database setup
+- **Database Schema Functions**: Access the DataJoint database schemas
+- **Session-Level Data Loading**: Load session-level information and metadata
+- **Trial-Level Data Loading**: Load detailed trial-level data for analysis
+- **Behavioral Event Data Loading**: Load specific behavioral events like licks and proximity sensor data
+- **Analysis and Performance Functions**: Compute performance metrics and provide session analysis
+- **Complete Data Loading Example**: Load all available data for a comprehensive analysis
+- **Data Format Options**: Support both DataFrame and DataJoint formats for flexibility
+- **Error Handling and Edge Cases**: How functions handle common edge cases
+
+**Key functions demonstrated**:
+```python
+# Load configuration from file
+config = load_config(display_path=True)
+print("Configuration loaded:")
+
+# Retrieve animal_id and session for a given setup
+animal_id, session = get_setup("ef-rp13") ## "ef-rp13" is the name of the setup
+print(f"Setup 'ef-rp13' current animal_id: {animal_id}, session: {session}")

+# Filter sessions by date range

+print(f"Sessions for animal {animal_id} in 2025:")
+print(sessions_filtered.head())

+# Remove aborted trials from the dataset
