Correction

We noticed a one-digit error on the tandem repeat number at the MIRU 20 after the publication of our article [1]. This was due to a typing error. The tandem repeat number at the MIRU 20 should be 2 instead of 1. All the figures indicating the tandem repeat number at the MIRU 20, i.e. the fifth digit of the VNTR profile from the left end of the set of digits, should be corrected in the text and correct information is provided in the revised Table 1. The first 12 digits of the VNTR profiles in the Methods part and Results part as well as in the Table 1 should read as 223325173533- instead of 223315173533- (Table 1).
