Hi there.
I have used a list of mature miRNAs to find out which ones are connected to two diseases of my interest. One with suffices (hsa-miR-xxx-3p/5p) wherever applied and the other without suffices (hsa-miR-xxx). In both cases pre-miRNA (hsa-mir-xxx) outputs were reported while I had input mature miRNAs (hsa-miR-xxx) only.
I also found that the sufficed inputs were not taken into consideration in forming the network, once removed the relevant pre-miRNAs were shown to form a disease-miRNA network.
