Create Data Sets from a Subset of Signal Channels

You can create a new data set in the System Identification app by extracting subsets of input and output channels from an existing data set.

To create a new data set from selected channels:

  1. In the System Identification app, drag the icon of the data from which you want to select channels to the Working Data rectangle.

  2. Select Preprocess > Select channels to open the Select Channels dialog box.

    The Inputs list displays the input channels and the Outputs list displays the output channels in the selected data set.

  3. In the Inputs list, select one or more channels in any of following ways:

    • Select one channel by clicking its name.

    • Select adjacent channels by pressing the Shift key while clicking the first and last channel names.

    • Select nonadjacent channels by pressing the Ctrl key while clicking each channel name.

    Tip

    To exclude input channels and create time-series data, clear all selections by holding down the Ctrl key and clicking each selection. To reset selections, click Revert.

  4. In the Outputs list, select one or more channels in any of following ways:

    • Select one channel by clicking its name.

    • Select adjacent channels by pressing the Shift key while clicking the first and last channel names.

    • Select nonadjacent channels by pressing the Ctrl key while clicking each channel name.

    Tip

    To reset selections, click Revert.

  5. In the Data name field, type the name of the new data set. Use a name that is unique in the Data Board.

  6. Click Insert to add the new data set to the Data Board in the System Identification app.

  7. Click Close.
