Trained on large scale macaque brain data-set from different sites.
Parts of codes are borrowed from nn-UNet and nn-Former
If you use these models, pleast cite our previous works on macaque brain MRI, which provide the training data:

The docker image has been uploaded onto DockerHub, download it by using the following command
docker pull wxyabc/bets_formers:1.0
docker run -it --gpus=all --ipc=host --name "NAME" wxyabc/bets_formers:1.0 /bin/bash
Follow the inference instruction in the bottom for brain extraction and tissue segmentation.
This software was originally designed and run on a system running Ubuntu 18.01, with Python 3.6, PyTorch 1.8.1, and CUDA 10.1. For a full list of software packages and version numbers, see the Conda environment file environment.yml.
This software leverages graphical processing units (GPUs) to accelerate neural network training and evaluation; systems lacking a suitable GPU will likely take an extremely long time to train or evaluate models. The software was tested with the NVIDIA RTX 2080 TI GPU, though we anticipate that other GPUs will also work, provided that the unit offers sufficient memory.
We recommend installation of the required packages using the Conda package manager, available through the Anaconda Python distribution. Anaconda is available free of charge for non-commercial use through Anaconda Inc. After installing Anaconda and cloning this repository, For use as integrative framework：
conda env create -f environment.yml
source activate Macaque_Transformers
pip install -e .
The models need to know where you intend to save raw data and trained models. For this you need to set a few of environment variables：
gedit ~/.bashrc
Once the file is open in a text editor, add the following lines to the bottom:
export nnFormer_raw_data_base="xxx/xxx/xxx/nnFormer_raw_data_base"
export nnFormer_raw_data="xxx/xxx/xxx/nnFormer_raw_data_base/nnFormer_raw_data"
export RESULTS_FOLDER_nnFormer="xxx/xxx/xxx/nnFormer_trained_models"

This model intends to obtain a brain mask from macaque T1w MRI. The inference subject should be located in nnFormer_raw_data_base/nnFormer_raw_data/Task505_ss/imagesTs as "AAAAAA(DATASET_NAME)_BBB(SUBJECT_ID)_CCCC(MODALITY)". Now this version only supports T1w modality. So the example file name can be "Cynomolgus_001_0000.nii.gz". We have upload 3 subjects from different sites as examples. For more macaque data please see PRIMatE-DE.
nnFormer_predict -i nnFormer_raw_data_base/nnFormer_raw_data/Task505_ss/imagesTs -o 505_brain_mask -m 3d_fullres -t 505 -chk model_best (-f 0/1/2/3/4 if you need to specify model)
Brain mask can be generated in this step. Check the brain mask and manually correct it if necessary. Then it can be used to extract macaque brain images (from with-skull images) for tissue segmentation:
python extract_brain_by_505.py
This model would output 4 class label maps, including WM, GM, CSF, and Cerebellum&Brainstem.
nnFormer_predict -i nnFormer_raw_data_base/nnFormer_raw_data/Task504_2macaque/imagesTs -o OUTPUT_PATH -m 3d_fullres -t 504 -chk model_best (-f 0/1/2/3/4 if you need to specify model)
We prepare 5 models for each task. So you can ensemble the predictions from several models with the following command:
nnFormer_ensemble -f FOLDER1 FOLDER2 ... -o OUTPUT_FOLDER
