We acquired data from the same ieeg patient with two separate amplifiers: 1 amplifier recorded from a 1-cm spaced grid and 1 amplifier recorded from a 3-mm spaced grid. The start time, sampling frequency and filter settings are different for the two amplifiers but both amplifiers recorded the same task in the same patient. The event file would be the same, because the patient did the same task.
How can I keep the two files separate in BIDS/ieeg? Looking at the doc the only naming structure allowed is
sub-<label>[_ses-<label>]_task-<label>[_run-<index>]_ieeg.eeg. I see there is an option to have simultaneous recordings but I’m not sure how to differentiate it here.
Another option is to keep them separate using an additional field, such as acq or recording
Do you have any suggestions on how to store data from two different amplifiers?
