BIDS mixed sessions

bids

#1

Hi all,

The dataset I’m working with has participants with a mixed number of sessions. Some have one session, others, more than one.

When organizing into BIDS, is it in keeping with the structure for all participants have the data in a sess directory?

So for participants with single sessions the structure is:
subj1 > sess-01 > data

and for multiple sessions:
subj2 > sess-01 > data
subj2 > sess-02 > data

Thanks.

Looks fine to me.
You could run a validator, though, in any case.

Yes, keeping your data within a session directory is BIDS compliant.

Note: In case your example was your proposed bids structure; it should be sub-1 not subj1, and ses-1 not sess-01.

Best,
James
