piRNApredictor is a software for predicting piRNA sequences.Identifying piwi-interacting RNAs (piRNAs) of non-model organisms is a difficult problem because piRNAs lack conservative secondary structure motifs and sequence homology between different species. In literatures, a method based on position-specific base usage was proposed to predict piRNAs with the support of genome data. For organisms without genome data, an efficient computational method is urgently required to identify and characterize their piRNAs. In this software, a k-mer method is used to identify piRNA sequences, and it performs with a precision of over 90% and a sensitivity of over 60%.
