The tests were runned separatly for amino-acid and nucleotides as they didn't have the same behavior. Indeed, the parameter sets have a greater effect on nucleotide than on amino-acid.

For the nucleotide sequences, as the time spent screening increased, there was a corresponding increase in the number of hits. The amino acid sequences did not exhibit a similar trend. For the nucleotide sequences screened, nucleotide parameter 3 allowed the program to find significantly more hits as the number of mutations increased as compared to the nucleotide default parameters. Compared to the nucleotide sequences, no set of BLAST parameters tested affected the program’s ability to find hits as a function of time for amino acid sequences.
