The more of the sequence that is analyzed, the higher confidence we have in the answer. This is why we never produce an identification report using anything other than the entire sequence.
The analysis of DNA sequence data is a complex process. We use the same high accuracy reference method to interpret your data that we use to create our library entries. This is not the case with other commercial solutions. There are several steps which require an experienced scientist to make decisions about DNA sequence quality, DNA sequence assembly and phylogenetic relatedness in order to correctly analyze and interpret the data. Results of the highest quality and accuracy are obtained with our manual process of data analysis and interpretation.
