I am very new to datalad. I would like to search through available data repos and find data sets (specifically, phase/frequency dsets to use for B0 correction) with certain keys in their JSONs.
I have been going through the help/intros and trying various search features, but I would like to check that I am understanding the search correctly. My key of interest is EffectiveEchoSpacing, and so I searched as follows:
datalad search EffectiveEchoSpacing
search(ok): /data/PROJECTS/datasets.datalad.org/openfmri/ds000223 (dataset)
which returned 1 dataset. Basically, I was surprised that only 1 dataset would be returned. Is that correct? Are there other options/information I should be providing?
