To clear a custom user call
If a custom user call has been entered for an allele in the project, you always have the option of clearing the call. When you clear a custom user call, the call is reset to the default value of blank (no call is displayed). To clear a custom user call, right-click in the appropriate User Call field, and on the context menu that opens, click Clear User Call. After you clear a custom user call, the cell is again highlighted in the color that is specified for “Flagged” for the STR Analysis viewer, with the default value being a golden yellow.
