Data Lab node
Signal Channels
Picks channels from a Signal by number, range or name — “1-8”, “9-16”, “Fp1, Fp2, O1” — in the order written; empty keeps every channel. Rate, unit and time travel unchanged, so the result goes straight into EEG Plot, FFT EEG, EEG Stream Send or any Data Lab node. Several of these split one stream into parts.
