Hi, For mRNA DE expression, the code used is

dataNorm <- TCGAanalyze_Normalization(tabDF = dataPrep,
                                  geneInfo = geneInfo,
                                  method = "gcContent")

However, what should I use for miRNAs in

dataNorm <- TCGAanalyze_Normalization(tabDF = dataPrep,
                                  geneInfo = ??,
                                  method = "??")

Next question Is there a way to use "TMM" instead of "quantile" during filtration ?

dataFilt <- TCGAanalyze_Filtering(tabDF = dataNorm,
                              qnt.cut = 0.25,
                              method='quantile')
