In this study, Shu et al characterized the potential deciding features of transportable microRNAs. They analyzed all publicly available microRNAs including a total of 34,612 from 194 species, and ranked them by the transportable probability. The Xeno-miR module has included the top 3000 miRNAs from the result and overlapped the xeno-species with the detected data.
Including the predicted transportable miRNAs may return a very large data. Users can try not to include them at the first time, and if the data size is reasonable, users can include the predicted miRNAs later.
