High confidence microRNAs

I promised a while ago to provide more information about the miRBase website features associated with the new “high confidence” microRNA set, as described in our 2014 NAR paper. First, some background. Here is a figure showing the growth of the number of sequences deposited in miRBase, and the number of papers in Pubmed that [...]
