fmriprep: A Robust Preprocessing Pipeline for fMRI Data¶
fmriprep is a functional magnetic resonance imaging (fMRI) data
preprocessing pipeline that is designed to provide an easily accessible,
state-of-the-art interface that is robust to variations in scan acquisition
protocols and that requires minimal user input, while providing easily
interpretable and comprehensive error and output reporting.
It performs basic processing steps (coregistration, normalization, unwarping,
noise component extraction, segmentation, skullstripping etc.) providing
outputs that can be easily submitted to a variety of group level analyses,
including task-based or resting-state fMRI, graph theory measures, surface or
volume-based statistics, etc.
fmriprep performs minimal preprocessing. Here we define ‘minimal preprocessing’ as motion correction, field unwarping, normalization, bias field correction, and brain extraction. See the workflows for more details.
fmriprep pipeline uses a combination of tools from well-known software
packages, including FSL, ANTs, FreeSurfer and AFNI.
This pipeline was designed to provide the best software implementation for each
state of preprocessing, and will be updated as newer and better neuroimaging
software become available.
This tool allows you to easily do the following:
- Take fMRI data from raw to fully preprocessed form.
- Implement tools from different software packages.
- Achieve optimal data processing quality by using the best tools available.
- Generate preprocessing quality reports, with which the user can easily identify outliers.
- Receive verbose output concerning the stage of preprocessing for each subject, including meaningful errors.
- Automate and parallelize processing steps, which provides a significant speed-up from typical linear, manual processing.
More information and documentation can be found at https://fmriprep.readthedocs.io/
fmriprep is built around three principles:
- Robustness - The pipeline adapts the preprocessing steps depending on the input dataset and should provide results as good as possible independently of scanner make, scanning parameters or presence of additional correction scans (such as fieldmaps).
- Ease of use - Thanks to dependence on the BIDS standard, manual parameter input is reduced to a minimum, allowing the pipeline to run in an automatic fashion.
- “Glass box” philosophy - Automation should not mean that one should not
visually inspect the results or understand the methods.
fmriprepprovides visual reports for each subject, detailing the accuracy of the most important processing steps. This, combined with the documentation, can help researchers to understand the process and decide which subjects should be kept for the group level analysis.
