BIDS mandates that every electrophysiology recording (MEG, EEG, iEEG) ship a sibling _channels.tsv with one row per channel describing name, type and units (REQUIRED) plus optional sampling / filter / status / description columns. BidsChannel is the in-memory row record and the static BidsChannel::readTsv / BidsChannel::writeTsv functions perform the TSV round-trip via BidsTsv. The BIDS channel-type vocabulary (MEGMAG, EEG, ECOG, SEEG, DBS, TRIG, …) maps to FIFF channel kinds through the tables in bids_const.h, so a channel record read from a BIDS dataset can be merged into a FIFFLIB::FiffInfo without an additional translation layer.
