Behavior Metadata without (tsv) Event Data Related to a Neuroimaging Data

Perhaps it would be useful to have this directory in some of the example datasets…

yes, the phenotype directory is not very well advertised, I agree. See also this issue and the PR linked therein. Further improvements in the form of a PR are welcome.

this is one example: OpenNeuro

the issue is that for each subject there are different numbers of medications/questionnaires given

mmmh, I see. Why would it not work if each participant is a row and you make a column for each medication?

I assume that Lev, Ras, Sel, Pr are some kinds of medication … because that’s what they seem to me from your example.

Example: /phenotype/myfile.tsv

participant_id	dose_lev	dose_ras	dose_sel	dose_pr
sub-01	0.25	1	n/a	n/a
sub-02	n/a	n/a	5	1.5

and then in the accompanying /phenotype/myfile.json you put something like:

{
    "dose_lev": {
        "Description": "Dosage of Lev",
        "Units": "mg"
    }
    ...
}
