Direct Inference in Your OWN CT scans

1. Put your all CT scans with nii.gz prefix in one directory. For example, /home/data/ct/.
2. Run following code.

conda create -n universalmodel python=3.7
conda activate universalmodel
pip install torch==1.11.0+cu113 torchvision==0.12.0+cu113 torchaudio==0.11.0 --extra-index-url https://download.pytorch.org/whl/cu113 
## please modify according to the CUDA version in your server
pip install 'monai[all]'
pip install -r requirements.txt
cd pretrained_weights/
wget https://www.dropbox.com/s/jdsodw2vemsy8sz/swinunetr.pth
cd ../
python pred_pseudo.py --data_root_path PATH_TO_IMG_DIR --result_save_path PATH_TO_result_DIR 
## For example: python pred_pseudo.py --data_root_path /home/data/ct/ --result_save_path /home/data/result

0. Preliminary

python3 -m venv universal
source /data/zzhou82/environments/universal/bin/activate

git clone https://github.com/ljwztc/CLIP-Driven-Universal-Model.git
pip install torch==1.11.0+cu113 torchvision==0.12.0+cu113 torchaudio==0.11.0 --extra-index-url https://download.pytorch.org/whl/cu113
pip install 'monai[all]'
pip install -r requirements.txt
cd pretrained_weights/
wget https://github.com/Project-MONAI/MONAI-extra-test-data/releases/download/0.8.1/swin_unetr.base_5000ep_f48_lr2e-4_pretrained.pt
wget https://www.dropbox.com/s/lh5kuyjxwjsxjpl/Genesis_Chest_CT.pt
cd ../

Dataset Pre-Process

1. Download the dataset according to the dataset link and arrange the dataset according to the dataset/dataset_list/PAOT.txt.
2. Modify ORGAN_DATASET_DIR and NUM_WORKER in label_transfer.py
3. python -W ignore label_transfer.py

Current Template

How expand to new dataset with new organ?

1. Set the following index for new organ. (e.g. 33 for vermiform appendix)
2. Check if there are any organs that are not divided into left and right in the dataset. (e.g. kidney, lung, etc.) The RL_Splitd in label_transfer.py is used to processed this case.
3. Set up a new transfer list for new dataset in TEMPLATE (line 58 in label_transfer.py). (If a new dataset with Intestine labeled as 1 and vermiform appendix labeled as 2, we set the transfer list as [19, 33])
4. Run the program label_transfer.py to get new post-processing labels.
