  1. TopHat-fusion reports approximately 200 times more raw candidates than CRAC; this ratio increases after filtering. Comparison with the set of validated chRNAs by Edgren et al. [27] shows that both the filtered and unfiltered predictions of CRAC and TopHat-fusion include respectively 20 and 21 true chRNAs and they agree for 17 of them.
