SNP Variables to Keep 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 kept 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 Keep:
| 8 | Specify the SNP Data Set. |
All of the variables in the specified data set are displayed in the Available Variables field.
| 8 | Examine the list of available variables. |
| 8 | Highlight one or more variables. Left-click a single variable, or hold down while left-clicking multiple variables. |
| 8 | Click  to add the highlighted variables to the SNP Variables to Keep in Output Data Set field, as shown below: |
