Usage

correct_dye_bias(raw)

correct_dye_bias2(raw)

Arguments

`raw`	Output of calling `read_idats`
`tissue`	Optional. If set to "blood", predefined reference values are used for normalization. Recommened when cell proportions are to be estimated.

Value

A modified raw object with dye-bias corrected intensities using RELIC for correct_dye_bias. A matrix of beta-values, either normalized (for normalize) or not (for dont_normalize).
