SNP Variables to Retain in Output Data Set
Use this field to specify the SNP variables that list the alleles (2 variables per marker) or genotypes (1 variable per marker, must be coded numerically) to be retained in the output data set. These variables are not used in the compression but are just copied to the output so that they are available for downstream analysis. These variables are in addition to other specified variables, which are kept by default.
Caution: Keeping all of the variables can result in large output data sets when the input data set contains a large number of columns and/or columns with large lengths.
To Specify One or More SNP Variables to Retain:
