from ezmsg.event.rate import EventRate


comps = {
    "NEO": NeoIteratorUnit(filepath="path/to/file", chunk_dur=0.05),
    "FILTER": FilterOnKey(key="spike"),
    "RATE": EventRate(bin_duration=0.05),
    "LOG": DebugLog()  # Print the output to the console
}
conns = (
    (comps["NEO"].OUTPUT_SIGNAL, comps["FILTER"].INPUT_SIGNAL),
    (comps["FILTER"].OUTPUT_SIGNAL, comps["RATE"].INPUT_SIGNAL),
    (comps["RATE"].OUTPUT_SIGNAL, comps["LOG"].INPUT),
)
ez.run(components=comps, connections=conns)
