# Write electrode positions to a temporary CSV, then read them back
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(400), nrow = 100, ncol = 4)),
  colData = S4Vectors::DataFrame(label = c("Fz", "Cz", "Pz", "Oz")),
  samplingRate = 100
)
pe <- applyMontage(pe, "10-20")
tmp <- tempfile(fileext = ".csv")
writeElectrodePositionsCSV(pe, tmp)

positions <- readElectrodePositionsCSV(tmp)
unlink(tmp)
