Note: You can specify as many as twelve (1 - 12) unique variables, depending on the number of QTL plots that you are comparing. Each variable must come from a unique Merge Input SAS Data Set (1-12).Use this field to specify the chromosome number variable from the Merge Input SAS Data Set (1-12) by which to merge. The values in this variable must be in the same order as the Base Key Variable specified in Key Chromosome Number Variable from Base Input SAS Data Set. This variable must also have valid values that match the values of the Base Key Variable. This must be a numeric variable.All of the variables in the specified data set are displayed in the Available Variables field.
