Dear all, motivated by a variety of MoBI studies currently being conducted in our group, I am thinking of proposing a new Brain Imaging Data Structure (BIDS) extension that addresses MoBI-specific needs for data sharing. This would also encompass flatscreen navigation data or 2D position streams from more conventional studies, so we can easily compare between recordings from different setups. I believe that the community will benefit a lot from clarifying properties specific to recording of spatial data. What are your thoughts on this idea? Is there any ongoing work for BIDS extension for movement data, or would you be interested in creating a new one?
Dear Marcie Zinn , motion capture data, if present, can be a valuable source of information for identifying EEG artifacts induced by physical motion. This would be one big motivation to establish standards for structuring mocap data so that it can be easily mapped to the EEG time series. The BIDS extension is not directly about dealing with artifacts but will facilitate the process.
Dear Klaus, thank you for this initiative. From the perspective of architecture / urban planning for health it would be very interesting to connect BIDS to spatial analysis tools such as Space Syntax or GIS. I have attached our paper using density, street network, isovists and space typologies to predict stress self-evaluation. It would be great to get in touch and think how to collaborate on this.
Hello Martin Knöll , this is an interesting idea. I have not looked into yet which data format / metadata will be useful for processing location data on a bigger scale. We are now working on a Google Doc for BIDS specifications for motion data, which currently focuses on motion on smaller scale. Here is the link to Google Doc https://docs.google.com/document/d/1iaaLKgWjK5pcISD1MVxHKexB3PZWfE2aAC5HF_pCZWo/edit?usp=sharing and the thread on GitHub to give you an impression on how the discussion is developing https://bids-specification.readthedocs.io/en/latest/06-extensions.html
Dear Martin,
Thanks for your interesting suggestion which I agree would be a great step forward. For now, however, the approach focusses on motion capture date as Sein already pointed out.
Sein is the person behind the BIDS extension for motion data and she is really pushing this project forward.
In case of questions, Sein will be the best qualified also for further discussions.
Best,
Klaus
