idet: idet - identify idats by a hash of the addresses

In schalkwyk/wateRmelon: Illumina 450 and EPIC methylation array normalization and metrics

idet - identify idats by a hash of the addresses

Description

idet - identify idats by a hash of the addresses

Usage

idet(idat)

Arguments

idat	cn be an idat file or the list produced by reading one with readIDAT()

Details

this function is a response to the fact that IlluminaHumanMethylationEPIC and EPICv2 idats both have the ChipType "BeadChip 8x5" but different manifests. They did have different numbers of addresses. Subsequently we have had some confusion.... This hash (certainly taken together with the ChipType) should be bombproof as an identifier. Warning: this is slow.

Value

three strings: ChipType, an md5 hash of the MidBlock (address vector) and if known the annotation name
