Normalizebetweenarrays和removebatcheffect
WebnormalizeBetweenArrays is the main normalization function for one-channel arrays, as well as an optional function for two-colour arrays. normalizeBetweenArrays uses utility functions normalizeMedianAbsValues, normalizeMedianAbsValues, normalizeQuantiles and normalizeCyclicLoess, none of which need to be called directly by users. WebnormalizeBetweenArrays normalizes expression values to achieve consistency between arrays. For two-color arrays, normalization between arrays is usually a follow-up step after normalization within arrays using normalizeWithinArrays.For single-channel arrays, within array normalization is not usually relevant and so normalizeBetweenArrays is the sole …
