In this command:

  • -it

    Run in interactive mode, allowing users to interact within the container.

  • --rm

    This option automatically removes the container after it exits, ensuring no residual containers remain.

  • -v /data/datasets/SMN4Lang:/input

    This option creates a volume mount, mapping the host directory /data/datasets/SMN4Lang to the container’s /input directory, allowing the container to access input data.

  • -v /data/datasets/SMN4Lang/preprocessed:/output

    This maps the output directory in the host to the container’s /output directory for saving processed data.

  • -v /data/datasets/SMN4Lang_smri:/smri

    This mounts a directory containing SMRI data(T1w, Freesurfer’s SUBJECTS_DIR) to the container’s /smri directory for application use.

  • -v /data/megprep/license.txt:/fs_license.txt

    This mounts the FreeSurfer license file into the container, ensuring it has access to the necessary permissions.

  • -v /data/nextflow.config:/program/nextflow/nextflow.config

    This mounts the Nextflow configuration file so the program inside the container can use it.

  • cmrlab/megprep:0.0.3

    This specifies the Docker image and version to run, where megprep is the image name, and 0.0.3 is the version.

  • -i /input

    This is a parameter passed to the program, specifying the input data directory as /input.

  • -o /output

    This parameter specifies the output data directory as /output.

  • --fs_license_file /fs_license.txt

    This passes the path to the FreeSurfer license file to the program, ensuring it can be recognized correctly.

  • --fs_subjects_dir /smri

    This specifies the separate SMRI data directory for use by the program.

  • --resume

    This flag allows the process to resume execution from the last completed step, which is useful for long-running tasks to avoid re-running completed steps.
