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.
