Running ASLPrep via Docker containers

For every new version of ASLPrep that is released, a corresponding Docker image is generated.

In order to run ASLPrep Docker images, the Docker Engine must be installed.

If you have used ASLPrep via Docker in the past, you might need to pull down a more recent version of the image:

$ docker pull pennlinc/aslprep:<latest-version>

ASLPrep can be run interacting directly with the Docker Engine via the docker run command line, or through a lightweight wrapper that was created for convenience.

Running ASLPrep directly interacting with the Docker Engine

Running containers as a user.

In order to run docker smoothly, it is best to prevent permissions issues associated with the root file system. Running docker as user on the host is to ensure the ownership of files written during the container execution.

A docker container can be created using the following command:

$ docker run -ti --rm \
    -v path/to/data:/data:ro \
    -v path/to/output:/out \
    pennlinc/aslprep:<latest-version> \
    /data /out/out \
    participant

For example:

$ docker run -ti -m 12GB --rm \
    -v $HOME/ds000240:/data:ro \
    -v $HOME/ds000240/derivatives:/out \
    -v $HOME/tmp/ds000240-workdir:/work \
    -v ${FREESURFER_HOME}:/fs \
    pennlinc/aslprep:<latest-version> \
    /data /out/aslprep-<latest-version> \
    participant \
    --participant-label '01'
    --fs-license-file /fs/license.txt
    -w /work
