Configuring the Data File Technique

You can configure the Data File technique options.

  1. Double-click the DOE component icon .

    The DOE Component Editor appears.

  2. From the General tab's DOE Technique list, select Data File.

    You can configure the Data File technique using *.txt, *.csv, *.xls, and *.xlsx file types.

    Note: The < > string is not supported when importing the data from the Excel spreadsheet.

  3. In the DOE Technique Options area, click Browse to select the file that you want to use with the technique.

    The file must contain a column of values for each factor (or a row if the Data is transposed option is selected), with columns separated by a tab, space, or comma. Use a header row to identify the parameters that correspond to the columns. You must enclose names or values with spaces in quotation marks.

    Note: A file parameter is added to the component to represent this file, allowing you to map in a new file at run time.

  4. Click Use Header Row if your data file has a header row containing the factor names. Specify which row contains the names of your factors by entering its corresponding number. If you do not select this option, you must explicitly specify which column each factor is associated with on the Factors tab.

  5. In the Data Starts on Row text box, specify the row in your file where the data begin by entering its corresponding number. If you are using a header row, the specified row must be greater than the header row.

  6. Click Scan for Parameters to scan the specified file for parameters to define. Names that are found are presented to select as factors (if specified as inputs) or responses (if specified as outputs). Any names found that are already defined as parameters are not presented in the list.

  7. From the Format list, select Levels or Values to specify whether the file contains level numbers (e.g., 1, 2, 3, etc.) or actual parameter values.

    If you select Levels, additional factor attributes are available to define how to calculate values from the levels.

  8. Click Store in model if you want the current file’s contents stored in the model for use when the component executes. If this option is not selected, the component attempts to access the specified file on the computer on which it executes.

  9. Click OK to save your changes and to close the DOE Component Editor.
