Write BDF (BioSemi Data Format) file — writeBDF • PhysioIO

Writes a PhysioExperiment object to BDF format (24-bit resolution).

Usage

writeBDF(x, path, patient_id = "X", recording_id = "X")

Arguments

x: A PhysioExperiment object.
path: Output file path.
patient_id: Patient identification string.
recording_id: Recording identification string.

Value

Invisible NULL.

Details

BDF is a 24-bit extension of EDF providing higher resolution than the standard 16-bit EDF format. It is commonly used with BioSemi acquisition systems but can be used for any high-resolution physiological data.

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000), nrow = 100, ncol = 10)),
  colData = S4Vectors::DataFrame(label = paste0("Ch", 1:10)),
  samplingRate = 100
)
tmp <- tempfile(fileext = ".bdf")
writeBDF(pe, tmp)
unlink(tmp)
