Comparison of alignment and normalization . I will take the message that TMM and DESeq/2 normalization are the best to avoid strong bias if we consider to have a small proportion of DE miRNAs. For the alignments, here you have another comparison for miRNAs annotation: https://rawgit.com/lpantano/tools-mixer/master/mirna/mirannotation/stats.html
