reIdentify: Re-identify IDATs by restoring scrambled SNP intensities

In zwdzwd/sesame: SEnsible Step-wise Analysis of DNA MEthylation BeadChips

Re-identify IDATs by restoring scrambled SNP intensities

Description

This requries setting a seed with a secret number that was used to de-identify the IDAT (see example). This requires a secret number that was used to de-idenitfy the IDAT

Usage

reIdentify(path, out_path = NULL, snps = NULL, mft = NULL)

Arguments

path	input IDAT file
out_path	output IDAT file
snps	SNP definition, if not given, default to SNP probes
mft	sesame-compatible manifest if non-standard

Value

NULL, changes made to the IDAT files

Examples

temp_out <- tempfile("test")

set.seed(123)
reIdentify(system.file(
    "extdata", "4207113116_A_Grn.idat", package = "sesameData"), temp_out)
unlink(temp_out)
