Figure 7From: SeqDoC: rapid SNP and mutation detection by direct comparison of DNA sequence chromatogramsPoor sequence quality. A poor quality sequence (in this case the reference sequence, top) unavoidably causes a noisy difference profile. However SeqDoC still successfully highlights nucleotides which differ between the sequences. In this case the C at position 390 in the reference sequence becomes a mixed T/C peak at position 398 in the test sequence.Back to article page
