[i] Break down of error statistics derived from performance testing using Method 2 (see Methods section) applied to both the MegaBACE dye-primer and dye-terminator set. Table lists all possible error combinations. For example, for the set MB_prim there were 12,192 correct calls made by LifeTrace where Phredhad a substitution error at the same position compared to 10,727 wherePhred was correct and LifeTrace had a substitution error and 14,069 cases where both basecallers had a substitution error. Mean BLAST hit length refers to the length of the high scoring sequence alignment between the called sequence and the finished, true consensus sequence. CalledNs are counted as bases and contributed to substitution and insertion errors.
