Pyneal -- real-time fMRI Analysis Software

Pyneal is an open source software package to support real-time functional magnetic resonance imaging (fMRI). It is entirely Python-based and depends exclusively on free, open source neuroimaging libraries.

It allows users to:

  • access functional MRI data in real-time
  • compute on-going analyses throughout a scan
  • monitor data quality
  • share analysis results with remote devices (e.g. send results to an experimental task presenting neurofeedback to participants)

It currently supports data formats used across 3 major MRI manufacturers: GE, Siemens, Philips.

In addition to allowing users to compute basic, ROI-based analyses during a scan, Pyneal also provides a simple framework for designing and writing customized analyses that can be computed across the whole brain volume at each timepoint.

Documentation

Please see Pyneal Docs for full documentation of this package, including:

  • Overview
  • Installation/Setup
  • Usage
  • Customizing analyses
  • Simulating fMRI environments for testing
  • Troubleshooting

Versioning

Commits to master should be accompanied by updating the CHANGELOG.md file and creating a new version release tag.

Version naming should follow semantic versionsing conventions as closely as possible.

After commiting changes, add a tag by git tag -a v<version-number>. Push the tag to the remote along with the rest of the code with git push origin <tag-name>

Code conventions

To ensure readability and consistency in code stylinh, please use a tool like flake8 to ensure your changes conform to PEP8 style guidelines
