From: Hierarchical Event Descriptor library schema for EEG data annotation
Example of an accompanying events JSON sidecar that lists the HED tags used in annotating the artifacts example (sub-eegArtifactTUH). Required BIDS columns are onset and duration. When annotating HED-SCORE events, the column annotation_type is added to describe with the levels and HED tags that are used. The column ‘channel’ is added to describe which channels in the BIDS _channels.tsv file the annotation corresponds to. This _channels.tsv file contains the montage in the dataset.
