ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONmandatory if this field is used:• The first information item is the electropherogram image reference / EIR. Itshall contain an alphanumeric reference up to 8 characters, which is unique foreach image. If none has been assigned, enter 999. This is a unique identifier.• The second information item is the electropherogram storage type / EST. Thisis a string of up to 4 characters, representing the file type suffix for theelectropherogram. The data is stored in “fsa”, “hid” or “----” The dashes may besubstituted with character strings for other format types as they become available.• The third information item is the image data descriptor / IDD of theelectropherogram contained in this subfield. If the data is stored externally, enterthe filename. This is a Unicode string of up to 200 characters. An example is“NIST Run 5 Well A06 12 Jan 11”• The fourth information item is the electropherogram data/ ELPD. This shall bestored in base-64 format.• The fifth information item is optional. It is the electropherogram screenshot /EPS. This may be an image captured during the analysis. This shall be stored inbase-64 format.8.18.20 Field 18.020: DNA genotype distribution / DGDThis field contains informative genotype representation type of DNA information. It is anoptional field. The entry is numeric:0 = Likelihood1 = Probability8.18.21 Field 18.021: DNA genotype allele pair / GAPThis field is only present if Field 18.020: DNA genotype distribution / DGD has avalue. It is used for low-template, mixture or stain scenarios only. It is comprised of arepeating subfield that occurs once for each allele pair. Allele calls are captured in Field18.016: Autosomal STR, X-STR and Y-STR / STR. Each subfield contains thefollowing information items.• The first information item is the genotype locus reference / GLR. The currentvalid loci for Autosomal, Y and X-STRs are maintained by NIST and areavailable at http://www.nist.gov/itl/iad/ig/ansi_standard.cfm . The GLR is anumeric entry with up to 3 characters per locus. The maximum value of 200listed in Table 92 is to allow for potential additions to the loci reference table.• The second information item is the allele pair / ALP. This is a numericinformation item containing the allele pair data of up to 9 numeric characters382
