SPM BIDS App

Description

BIDS App containing an instance of the SPM12 software.

Documentation

Extensive documentation can be found in the SPM manual.

Usage

To launch an instance of the container and analyse some data in BIDS format, type:

bash $ docker run bids/spm bids_dir output_dir level [--participant_label PARTICIPANT_LABEL [PARTICIPANT_LABEL ...]] [--config CFG_FILE]

For example, to run an analysis in participant level mode, type:

bash $ docker run -ti --rm \ -v /tmp:/tmp \ -v /var/tmp:/var/tmp \ -v /path/to/local/bids/input/dataset/:/data \ -v /path/to/local/output/:/output \ bids/spm \ /data /output participant --participant_label 01

For example, to run an analysis in group level mode with a user-defined pipeline, type:

bash $ docker run -ti --rm \ -v /tmp:/tmp \ -v /var/tmp:/var/tmp \ -v /path/to/local/bids/input/dataset/:/data \ -v /path/to/local/output/:/output \ -v /path/to/local/cfg/:/cfg \ bids/spm \ /data /output group --config /cfg/my_pipeline_group.m

To build the container, type:

bash $ docker build -t <yourhandle>/spm12 .

Configuration file

The configuration file is a MATLAB script detailing the analysis pipeline to be executed. Two struct variables, BIDS and BIDS_App are available from within the script, containing details from the command line and the BIDS-formatted dataset. In particular, the BIDS structure can be queried using the spm_BIDS() function (see this). The default configuration files for first and second level analyses are pipeline_participant.m and pipeline_group.m. A template for a single configuration file for all levels could be as follow:

```bash if strcmp(BIDS_App.level,'participant') % First level analysis

% Get T1-weighted image filename for given subject:
% a = spm_BIDS(BIDS,'data', 'modality','anat', 'type','T1w');
% ...

else % Second level analysis

% The name of the directory containing first level outputs is stored in:
% BIDS_App.outdir
% ...

end ```

Error Reporting

If you have a specific problem with the SPM BIDS App, please open an issue on GitHub.
