Check this box to use the annotation label variable, instead of the marker variable name, to create names for the expanded genotype columns.
The expanded genotype columns contain one column per allele at each marker. The allele is appended to either the annotation label or the marker variable name to create the variable name.
Note: If Alleles is selected as the Format of Marker Variables, then the Annotation Label Variable is automatically used.
If no annotation data set is specified, the string Marker appended to the marker number is used as the annotation label.
