Dockerfile creates a base docker container that can execute the new version 2.1 of brainageR (author James Cole) which can be found on https://github.com/james-cole/brainageR. BrainageR is software for generating a brain-predicted age value from a raw T1-weighted MRI scan.
You can analyze a raw T1-weighted MRI scan with the following command:
docker run --rm -it -v ${PWD}/your_data:/data ghcr.io/psadil/brainager_dockerfile:main -f /data/sub-01_T1w_defaced.nii -o /data/sub-01_T1w_defaced.csv
sub-01_T1w_defaced.nii is the name of the raw T1-weighted MRI scan decompressed in nii format placed in your_data folder, and subj01_brain_predicted.age.csv is the .csv file where the age predictions are saved.
