This tool allows you to run the PITA algorithm on your choice of UTRs and microRNAs. PITA starts by scanning the UTR for potential microRNA targets (using the supplied seed matching tools) and then scores each site using the method described in Kertesz et al., The role of site accessibility in microRNA target recognition, Nature Genetics 2007.The tool is limited to 100 targets per run. For heavy-duty microRNA prediction, please download the PITA executable and run it on your own machine.
