For an ingested (downloaded) dataset + the probe objects are not persisted (their identifiers are minted at + construction time), so this port reconstructs the same table directly from + the documents: the ``epochprobemap`` of each ``epochfiles_ingested`` doc + tells us which probes appear in which epoch, and the per-epoch timing lives + in the ``daqreader_mfdaq_epochdata_ingested`` doc keyed by the shared + ``epochid`` (the same key that joins ``stimulus_bath`` and + ``openminds_stimulus``). ``ProbeDocumentIdentifier`` is therefore the + probe's *element* document id (stable within a load and consistent with + :func:`probe`), which is what the downstream ``combinedSummary`` join uses. Returns a DataFrame with columns: EpochNumber, EpochDocumentIdentifier, ProbeDocumentIdentifier, - SubjectDocumentIdentifier, MixtureName, MixtureOntology, - ApproachName, ApproachOntology + SubjectDocumentIdentifier, local_t0, local_t1, global_t0, global_t1, + MixtureName, MixtureOntology, ApproachName, ApproachOntology + (columns that are empty across every row are dropped, matching MATLAB).
