string: Based on our previous experience (Palacios and Gamallo, 1998; Lim et al., 2011, 2012; Stewart et al., 2000; Wang et al., 2010; Lowery et al., 2009; Li et al., 2013; Trevino et al., 2010), we selected four predicted target-miRs with prediction scores of greater than 80 because scores greater than 80 are most likely to be real.
