Hi I'm wondering if some documentation somewhere lists which criteria were used to include miRNA -> mRNA target sets in the RmiR.Hs.miRNA package? For example, say for TargetScan , which version of TargetScan was used to calculate targets? What were the cutoff's for PCT, Total Context Score, conservation and which seed matches were included? Similar questions for the other algorithms! I haven't been able to find this information anywhere online and it would be extremely useful!
