This repository contains the code of GLIMS.

GLIMS ranked in the top 5 among 65 unique submissions during the validation phase of the Adult Glioblastoma Segmentation challenge of BraTS 2023.

git clone https://github.com/yaziciz/GLIMS.git
cd GLIMS

With your virtual environment activated, install the project's dependencies:

pip install -r requirements.txt

The GLIMS model can be trained by the given script on the BraTS 2023 dataset:

python main.py --output_dir <output_directory> --data_dir <data_directory> --json_list <json_list_file> --fold <fold_id>

By using the pre-trained model, the validation phase can be performed as follows:

python post_validation.py --output_dir <output_directory> --data_dir <data_directory> --json_list <json_list_file> --fold <fold_number> --pretrained_dir <pretrained_model_directory>

To test GLIMS by using the ensemble method on the unannotated BraTS 2023 dataset, the following script can be used:

python test_BraTS.py --data_dir <validation_data_directory> --model_ensemble_1 <model_1_path> --model_ensemble_2 <model_2_path> --output_dir <output_directory>

The model_ensemble_1 and model_ensemble_2 variables represent the fold 2 and fold 4 models, as indicated in our challenge submission paper on arXiv.
