Commandline Usage

Introduction

The Connectome Mapper 3 BIDS App takes as principal input the path of the dataset that is to be processed. The input dataset is required to be in valid BIDS format, and it must include at least one T1w or MPRAGE structural image. We highly recommend that you validate your dataset with the free, online BIDS Validator.

Commandline Arguments

The command to run Connectome Mapper 3 follow the BIDS-Apps definition with additional options for loading pipeline configuration files.

usage: connectomemapper3 [-h]
                         [--participant_label PARTICIPANT_LABEL [PARTICIPANT_LABEL ...]]
                         [--anat_pipeline_config ANAT_PIPELINE_CONFIG]
                         [--dwi_pipeline_config DWI_PIPELINE_CONFIG]
                         [--func_pipeline_config FUNC_PIPELINE_CONFIG]
                         [--number_of_participants_processed_in_parallel NUMBER_OF_PARTICIPANTS_PROCESSED_IN_PARALLEL]
                         [--fs_license FS_LICENSE] [-v]
                         bids_dir output_dir {participant,group}

Positional Arguments

bids_dir The directory with the input dataset formatted according to the BIDS standard.
output_dir The directory where the output files should be stored. If you are running group level analysis this folder should be prepopulated with the results of theparticipant level analysis.
analysis_level

Possible choices: participant, group

Level of the analysis that will be performed. Multiple participant level analyses can be run independently (in parallel) using the same output_dir.

Named Arguments

--participant_label
 The label(s) of the participant(s) that should be analyzed. The label corresponds to sub-<participant_label> from the BIDS spec (so it does not include “sub-“). If this parameter is not provided all subjects should be analyzed. Multiple participants can be specified with a space separated list.
--anat_pipeline_config
 Configuration .txt file for processing stages of the anatomical MRI processing pipeline
--dwi_pipeline_config
 Configuration .txt file for processing stages of the diffusion MRI processing pipeline
--func_pipeline_config
 Configuration .txt file for processing stages of the fMRI processing pipeline
--number_of_participants_processed_in_parallel
 The number of subjects to be processed in parallel (One core used by default).
--fs_license Freesurfer license.txt
-v, --version show program’s version number and exit

Participant Level Analysis

To run the docker image in participant level mode (for one participant)

docker run -it --rm \
        -v /home/localadmin/data/ds001:/tmp \
        -v /media/localadmin/data/ds001/derivatives:/tmp/derivatives \
        -v /usr/local/freesurfer/license.txt:/tmp/code/license.txt \
        sebastientourbier/connectomemapper3:latest \
        /tmp /tmp/derivatives participant --participant_label 01 \
            --anat_pipeline_config /tmp/code/ref_anatomical_config.ini \
        (--dwi_pipeline_config /tmp/code/ref_diffusion_config.ini \)
        (--func_pipeline_config /tmp/code/ref_fMRI_config.ini \)

Note

The local directory of the input BIDS dataset (here: /home/localadmin/data/ds001) and the output directory (here: /media/localadmin/data/ds001/derivatives) used to process have to be mapped to the folders /tmp and /tmp/derivatives respectively using the -v docker run option.

Note

At least a configuration file describing the processing stages of the anatomical pipeline should be provided. Diffusion and/or Functional MRI pipeline are performed only if a configuration file is set.

Debugging

Logs are outputted into <output dir>/cmp/sub-<participant_label>/sub-<participant_label>_log-cmpbidsapp.txt.

Not running on a local machine? - Data transfer

If you intend to run connectomemapper3 on a remote system, you will need to make your data available within that system first. Comprehensive solutions such as Datalad will handle data transfers with the appropriate settings and commands. Datalad also performs version control over your data.
