I have a double stranded RNA (dsRNA) sequence (~300 nt long). Are there any bioinformatic tools to predict its products after cleavage by Dicer (presuming that it is already processed by Drosha).
I don't know whether any software do exactly what you are looking for, but I think you can predict miRNA from the dsRNAs if you able to tweak the available open source software, say for example miRDeep2 etc.
