Parameters | Import | Flag Filter Expression

Flag Filter Expression
Enter a SAS logical expression to filter data based on the Flag column specified in the design file. For example, specifying (Flag < 0) or (Flag > 5000) sets the imported intensity to missing when the Flag is less than 0 or larger than 5000 in original scale.
Leave this field blank if there is no Flag column in the design file or no filtering is needed.
To Specify a Flag Filter Expression:
Type the expression into the Flag Filter Expression text field.
