Table 1.

The performance of sirFAST with three simulated data sets. Each data set included 1 million reads. Note that 1% of the simulated reads in set 1 have one error respect to the reference, thus the best performance is to map 99% of the reads when the error tolerance of sirFAST is set to zero. In the second set, 2% of the reads have one error, therefore the best possible mappability ratio is 98% when the error tolerance is set to zero.
