how to add a level session in the participants.tsv #5

Hi,

If you want to import a level session, how to modify the participants.tsv file:

1st proposition: participant_id NIP acq_date sub-1-ses-1 nip_number 2010-06-28 sub-1-ses-2 nip_number 2010-06-25 sub-2-ses-1 nip_number 2010-07-01 sub-2-ses-2 nip_number 2010-05-23

2nd proposition: participant_id session NIP acq_date sub-1 ses-1 nip_number 2010-06-28 sub-1 ses-2 nip_number 2010-06-25 sub-2 ses-1 nip_number 2010-07-01 sub-2 ses-2 nip_number 2010-05-23

I didn't see this kind of information in the Bids specification. Not sure if it possible to add a field in the participants.tsv ?

Any idea ?

@isadenghien its already possible. I will create an example in a coming PR then.

I added some quick comments on this in the #6 review

Hi, Ok the solution is a specific field is already designed on the first line of the participants.tsv file like:

participant_id session_id session NIP acq_date

The solution is two things:

1) As you mention to add the session_id field to participants.tsv 2) That the download file reflects in the filename session if necessary like "ses-01_download"
