BIDS EEG data recording with pause

1

Dear all,

We have data collected with the EGI device. And we pause the recording when the participant has a break and continue the recording when the participant continues, which results in discontinuous recording in a single file.

I want to know if it’s acceptable to keep the discontinuous data or if I have to split it into multiple run files when converting to BIDS format? Thank you.

You can share your discontinuous data – see the RecordingType metadata in the specification, or this screenshot:

But I would clearly mention this in the README file as well.

Thanks for your response and kind reminder! It’s very useful.

Hi, Thank you for this solution. My group is facing a similar issue, so it is helpful to know that we can indicate discontinuous. I had a follow up about how best to name the BrainVision files in this case?

for example, for subject 630, we might have taken a pause during the session, so we have the following raw files:
630.eeg; 630.vhdr; 630.vmrk;
630b.eeg; 630b.vhdr; 630b.vmrk.

What would be best best way to name/structure these data in accordance with BIDS format?
