1. Download Internet Brain Segmentation Repository (IBSR) (or other dataset you want to try)
2. preprocess dataset

• training dataset $ python preprocess.py -i /path/to/IBSR/dataset -s IBSR_01 IBSR_02 IBSR_03 IBSR_04 IBSR_05 --input_image_suffix _ana_strip.nii.gz --output_image_suffix _preprocessed.nii.gz --label_suffix _segTRI_ana.nii.gz -f dataset_train.json --n_classes 4 --zooms 1. 1. 1.
• test dataset $ python preprocess.py -i /path/to/IBSR/dataset -s IBSR_11 IBSR_12 IBSR_13 IBSR_14 IBSR_15 --input_image_suffix _ana_strip.nii.gz --output_image_suffix _preprocessed.nii.gz --label_suffix _segTRI_ana.nii.gz -f dataset_test.json --n_classes 4 --zooms 1. 1. 1.
