****************** Install ****************** .. contents:: Table of Contents Summary =================== Pull docker container:: docker pull neurodata/ndmg_dev Run dmri participant pipeline:: docker run -ti -v /path/to/local/data:/data neurodata/ndmg_dev /data/ /data/outputs System Requirements ==================== .. TODO: update package versions The ndmg pipeline was developed and tested primarily on Mac OSX, Ubuntu (12, 14, 16, 18), and CentOS (5, 6); Made to work on Python 3.6; Is wrapped in a Docker container; Has install instructions via a Dockerfile; Requires no non-standard hardware to run; Has key features built upon FSL, Dipy, Nibabel, Nilearn, Networkx, Numpy, Scipy, Scikit-Learn, and others; Takes approximately 1-core, 8-GB of RAM, and 1 hour to run for most datasets. While ndmg is quite robust to Python package versions (with only few exceptions, mentioned in the installation guide), an example of possible versions (taken from the ndmg Docker Image with version v0.2.0) is shown below. Note: this list excludes many libraries which are standard with a Python distribution, and a complete list with all packages and versions can be produced by running pip freeze within the Docker container mentioned above. :: awscli==1.16.210 , boto3==1.9.200 , botocore==1.12.200 , colorama==0.3.9 , configparser>=3.7.4 , Cython==0.29.13 , dipy==0.16.0 , duecredit==0.7.0 , fury==0.3.0 , graspy==0.0.3 , ipython==7.7.0 , matplotlib==3.1.1 , networkx==2.3 , nibabel==2.5.0 , nilearn==0.5.2 , numpy==1.17.0 , pandas==0.25.0, Pillow==6.1.0 , plotly==1.12.9, pybids==0.6.4 , python-dateutil==2.8.0 , PyVTK==0.5.18 , requests==2.22.0 , s3transfer==0.2.1 , setuptools>=40.0 scikit-image==0.13.0 , scikit-learn==0.21.3 , scipy==1.3.0 , sklearn==8.0 , vtk==8.1.2 Installation Guide ================== .. TODO: add links to external packages Currently, the Docker image is recommended. ``pip`` and Github installations are also available. Docker -------------- .. _Dockerhub : https://hub.docker.com/r/neurodata/m3r-release/ .. _documentation : https://docs.docker.com/ The neurodata/m3r-release Docker container enables users to run end-to-end connectome estimation on structural MRI or functional MRI right from container launch. The pipeline requires that data be organized in accordance with the BIDS spec. If the data you wish to process is available on S3 you simply need to provide your s3 credentials at build time and the pipeline will auto-retrieve your data for processing. If you have never used Docker before, it is useful to run through the Docker documentation_. **Getting Docker container**:: $ docker pull neurodata/ndmg_dev *(A) I do not wish to use S3:* You are good to go! *(B) I wish to use S3:* Add your secret key/access id to a file called credentials.csv in this directory on your local machine. A dummy file has been provided to make the format we expect clear. (This is how AWS provides credentials) **Processing Data** Below is the help output generated by running **ndmg** with the ``-h`` command. All parameters are explained in this output. :: $ docker run -ti neurodata/ndmg_dev -h usage: ndmg_bids [-h] [--participant_label PARTICIPANT_LABEL [PARTICIPANT_LABEL ...]] [--session_label SESSION_LABEL [SESSION_LABEL ...]] [--run_label RUN_LABEL [RUN_LABEL ...]] [--bucket BUCKET] [--remote_path REMOTE_PATH] [--push_data] [--dataset DATASET] [--atlas ATLAS] [--debug] [--sked] [--skreg] [--vox VOX] [-c] [--mod MOD] [--tt TT] [--mf MF] [--sp SP] [--seeds SEEDS] [--modif MODIF] bids_dir output_dir This is an end-to-end connectome estimation pipeline from M3r Images. 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 the participant level analysis. optional arguments: -h, --help show this help message and exit --participant_label PARTICIPANT_LABEL [PARTICIPANT_LABEL ...] The label(s) of the participant(s) that should be analyzed. The label corresponds to sub- 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. --session_label SESSION_LABEL [SESSION_LABEL ...] The label(s) of the session that should be analyzed. The label corresponds to ses- from the BIDS spec (so it does not include "ses-"). If this parameter is not provided all sessions should be analyzed. Multiple sessions can be specified with a space separated list. --run_label RUN_LABEL [RUN_LABEL ...] The label(s) of the run that should be analyzed. The label corresponds to run- from the BIDS spec (so it does not include "task-"). If this parameter is not provided all runs should be analyzed. Multiple runs can be specified with a space separated list. --bucket BUCKET The name of an S3 bucket which holds BIDS organized data. You must have built your bucket with credentials to the S3 bucket you wish to access. --remote_path REMOTE_PATH The path to the data on your S3 bucket. The data will be downloaded to the provided bids_dir on your machine. --push_data flag to push derivatives back up to S3. --dataset DATASET The name of the dataset you are perfoming QC on. --atlas ATLAS The atlas being analyzed in QC (if you only want one). --debug If False, remove any old files in the output directory. --sked Whether to skip eddy correction if it has already been run. --skreg whether or not to skip registration --vox VOX Voxel size to use for template registrations (e.g. default is '2mm') -c, --clean Whether or not to delete intemediates --mod MOD Determinstic (det) or probabilistic (prob) tracking. Default is det. --tt TT Tracking approach: local or particle. Default is local. --mf MF Diffusion model: csd or csa. Default is csd. --sp SP Space for tractography. Default is native. --seeds SEEDS Seeding density for tractography. Default is 20. --modif MODIF Name of folder on s3 to push to. If empty, push to a folder with ndmg's version number. In order to share data between our container and the rest of our machine in Docker, we need to mount a volume. Docker does this with the -v flag. Docker expects its input formatted as: ``-v path/to/local/data:/path/in/container``. We'll do this when we launch our container, as well as give it a helpful name so we can locate it later on. **To run ndmg on data** :: docker run -ti -v /path/to/local/data:/data neurodata/ndmg_dev /data/ /data/outputs Pip ------------- ndmg relies on FSL, Dipy, networkx, and nibabel, numpy scipy, scikit-learn, scikit-image, nilearn. You should install FSL through the instructions on their website, then follow install other Python dependencies with the following:: pip install ndmg The only known packages which require a specific version are plotly and networkx, due to backwards-compatability breaking changes. Installation shouldn't take more than a few minutes, but depends on your internet connection. Github ----------- To install directly from Github, run:: git clone https://github.com/neurodata/ndmg cd ndmg python setup.py install
