Introducing MEG-BIDS

Dear All:

We are happy to introduce the MEG-BIDS: an extension to the Brain Imaging Data Structure for magnetoencephalography. MEG-BIDS is a principled solution to store, organize and share the typically-large data volumes produced with MEG. It builds on BIDS for MRI, and therefore readily yields a multimodal data organization by construction. This is particularly valuable for the anatomical and functional registration of MEG source imaging with MRI. With MEG-BIDS and a growing range of software adopting the standard (presently: Brainstorm, SPM, FieldTrip and MNE), the MEG community has a solution to minimize curation overheads, reduce data handling errors and optimize usage of computational resources for analytics. The standard also includes well-defined metadata, to facilitate future data harmonization and sharing efforts.

Please take a moment to read through the short manuscript that describes this initiative ( and try ou the 4 full MEG-BIDS datasets available for download:

  1. OMEGA Resting-State samples: Five minutes of eyes-open, resting-state MEG data is available for 5 subjects from The Open MEG Archive (OMEGA) .

  2. Brainstorm Auditory Example dataset: Brainstorm Auditory tutorial dataset

  3. MNESampledata: Sample data with visual and auditory stimuli

  4. OpenfMRI study ds000117: A multi-subject, multi-modal human neuroimaging dataset of 19 subjects participating in a visual task.

Your feedback and suggestions are important: please complete the short survey concerning this initiative, so that we can continue to improve the MEG-BIDS features:

Please also note that MEG-BIDS is presently being extended to EEG and e-phys data.

With best wishes,
