Write PhysioExperiment to BrainVision format

Saves a PhysioExperiment object to BrainVision format (three files: .vhdr header, .vmrk markers, .eeg binary data).

Usage

writeBrainVision(
  x,
  path,
  overwrite = FALSE,
  binary_format = c("IEEE_FLOAT_32", "INT_16", "INT_32"),
  assay_name = NULL
)

Arguments

x

A PhysioExperiment object.

path

Output path (without extension, or with .vhdr extension).

overwrite

Logical. If TRUE, overwrites existing files.

binary_format

Binary format for data: "IEEE_FLOAT_32" (default), "INT_16", or "INT_32".

assay_name

Assay to export. If NULL, uses default assay.

Value

Invisible NULL.

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000), nrow = 100, ncol = 10)),
  colData = S4Vectors::DataFrame(label = paste0("Ch", 1:10)),
  samplingRate = 100
)
base <- tempfile()
writeBrainVision(pe, base)
unlink(paste0(base, c(".vhdr", ".vmrk", ".eeg")))
