TIS prediction experiments by modified MetaTISA on simulated shotgun DNA fragments. The artificial shotgun sequences are sampled from E. coli K12 with fixed-length of 870 bp. The upstream minimum length means the minimum requisite amount of upstream bases used for scoring if it is less than 50 bp, and the TIS accuracy is the overall accuracy of both the internal and the external TISs. The supervised TIS parameters used for the experiments including those trained on the RefSeq annotations and the TriTISA annotations, with Markov models ranging from 0-order to 4th-order.
