I am working on analyzing some high throughput data and trying to quantify which miRNAs are differentially expressed and by how much in my experiments. To do this I planned to use mirDeep2 and mirBase to acquire my precursors and mature miRNAs for my mirDeep2 input, but my model (Mustela putorius furo) is not yet annotated on mirBase. I found annotations for pre-miRNA and miRNA on RNAcentral, but its not immediately clear to me whether those are the hairpins and mature miRNAs I need for mirDeep2 to run. If anybody has any advice on using RNAcentral for mirDeep2 or other alternative databases that might include ferret sequences that would be greatly appreciated!
