1. Data Preparation

• Download BCV dataset
• Preprocess the BCV dataset according to the uploaded nnUNet package.
• Training and Testing ID are in data/splits_final.pkl.

2. Training

cd CoTr_package/CoTr/run

• Run nohup python run_training.py -gpu='0' -outpath='CoTr' 2>&1 & for training.

3. Testing

• Run nohup python run_training.py -gpu='0' -outpath='CoTr' -val --val_folder='validation_output' 2>&1 & for validation.
