Can someone tell me how MEV deals with zero values in array datasets? For example a set of 100 genes and 2 conditions. Gene 25 in condition A is "0" but in condition B is "5" (after replicates of course). Is a Box-Cox transform done? Some sort of NNMF? I'm reading a lot about Inverse Hyperbolic Sine transformation, but my brain exploded. What does MEV perform associated with the log2 transformation of the data when importing (for example) GenePix datafiles.
