Steering Group executive summary, action items, and minutes

Date: Thursday February 4, 2021

Executive Summary

The Steering Group met to discuss the latest BEP updates. ASL and qMRI are close to being released with PET following soon after. We spent the majority of the meeting with the leads from BEP20: Eye Tracking. They are progressing nicely and starting to finalize their specification. They are having their Eye Tracking community review prior to escalating up to the BIDS community. They are reaching a consensus within their community. This extension will help BIDS continue to extend into more diverse windows into the brain and further unlock more multimodal studies.

Action items

N/A

Minutes

• ASL specification, examples, and validator are ready for release
• qMRI specification is merged. Working on examples and validator
• After ASL and qMRI are release, we will focus on getting PET incorporated

The Steering Group was joined by BEP20: Eye Tracking leads

• The community is reviewing the BEP
  • Trying to be public about the efforts
• BEP seeks to be a solution for different types of Eye Tracking experiments
  • Big use case is naturalistic stimuli
• BEP status
  • Most people are receptive to the BEP
  • There was a preprint released that is related to the BEP effort
    • BEP leads reached out and received good feedback from the authors
    • The preprint was a bit more high-level, but is compatible with the BEP
    • Preprint focused on how to report Eye Tracking in a paper rather than how to organize and share the data
• The community is sharing data
• BEP does have a constrained scope with a clear goal
  • Core aspect: position of the area and recording that along with the stimuli map
• BIDS is an interoperable standard
  • Community focused to wrap BEP into BIDS
  • Some colleagues have had trouble getting over the Brain Imaging part of BIDS
    • Could be an impediment to adoption
  • BIDS is a practical implementation, would rather be in BIDS
• Eye Tracking with EEG, MEG, and/or MRI is becoming more common
• We can use the existing infrastructure to continue unlocking multimodal studies
• One goal is to develop BIDS-Apps for Eye Tracking
• The conversion to markdown is done
  • Encountering challenges with the validator implementation
  • Examples have been generated
• Performing a within Eye Tracking community review
  • Ensuring the community is comfortable with the BEP
• One potential issue is time series representation conflicts
  • Coordinating with BEP29: Virtual and physical motion
  • Meeting with relevant stakeholders
• Balancing the validation with practical implementation
