RockWorks | Utilities | Columns | Filter
Use this RockWorks Utilities tool to remove or replace numeric values that fall below and/or above a specified value range. This tool does not remove entire rows or records, just the data values in the selected column.
Menu Options
- Input Column: Select from this drop-down list the name of the column in the datasheet that contains the data values to be removed or replaced.
- Low Stop: Insert a check in this box to remove/replace low values from the column.
- Stop Value: Type in the real number value below which values will be removed. You can activate either or both high and low filters.
- Replacement Text: If you would like to replace the filtered values with another numeric value or text string, click here and type that into this prompt. This provides a means for flagging special samples (e.g. "Below Detection") or setting the cell values to the cutoff values, in addition to simply leaving cells blank.
- High Stop: Insert a check in this box to remove high values from the column.
- Stop Value: Type in the real number value above which values will be removed.
- Replacement Text: If you would like to replace the filtered values with another numeric value or text string, click here and type that into this prompt.
