 1. Start with **`SysBio-Traj_index.csv`** to find the `model_id`, `model_name`, and simulation time range.
 2. Open **`Data/<model_id>/`** to access the trajectory, SBML file, and metadata for that model.
 3. Use **`scripts/simulate_sbml.py`** if you want to reproduce a trajectory from the released SBML + initial conditions.
+4. Use the companion [RegimeFlow repository](https://github.com/zhaoxixixi/RegimeFlow) for the model training and evaluation workflow built around this dataset.
