Importing Scalar Values from CSV Files

If required, you can import scalar values contained in a selected comma-separated values file (*.csv extension) into a multi-ROI, mesh, or graph.

Scalar values can be imported from either a Dragonfly-formatted CSV file, in which case all slots will be imported, or you can import scalar slots one-by-one from a generic CSV file that contains the required IDs and corresponding values.

Dragonfly-formatted CSV files are formatted in columns as follows: | Time Step | ID | Measurement (unit) |, and optionally | X-Coordinate (unit) | Y-Coordinate (unit) | Z-Coordinate (unit) |, if the CSV was exported from Dragonfly with the mesh coordinates. Generic CSV files must be formatted as: | ID | Value |. Other information, such as the slot title, slot dimension type, slot unit, and time step, must be entered manually.
  1. Right-click the required object in the Data Properties and Settings panel and then choose Import Scalar Values from a CSV File in the pop-up menu.

    The Scalar Values Slots Importer dialog appears.

  2. Check the Import scalar values slots from a Dragonfly CSV file format option, if the CSV file was exported from Dragonfly.

    Note If you are importing scalar values to a mesh, choose a scalar type — Face Scalar Values or Vertex Scalar Values — in the Scalar type drop-down menu.

    If you are importing scalar values to a graph, choose a scalar type — Edge Scalar Values or Vertex Scalar Values — in the Scalar type drop-down menu.

  3. Click Continue.
  4. Choose the required CSV file in the Import Data from File dialog.
  5. Click Open to import the scalar values slots from the selected CSV file.
  6. Save your changes, if required.
  1. Right-click the required object in the Data Properties and Settings panel and then choose Import Scalar Values from a CSV File in the pop-up menu.

    The Scalar Values Slots Importer dialog appears.

  2. Uncheck the Import scalar values slots from a Dragonfly CSV file format option, if you are importing values from a generic CSV file.

    The Imported slot information box appears in the dialog, as shown below.

    Note If you are importing scalar values to a mesh, choose a scalar type — Face Scalar Values or Vertex Scalar Values — in the Scalar type drop-down menu.

    If you are importing scalar values to a graph, choose a scalar type — Edge Scalar Values or Vertex Scalar Values — in the Scalar type drop-down menu.

  3. Enter the required Imported slot information, which includes the Slot title, Slot dimension type, Slot unit, and Time step, that corresponds to the scalar values that will be imported.
  4. Choose the required CSV file in the Import Data from File dialog.
  5. Click Open to import the scalar values slot from the selected CSV file.
  6. Import additional slots, as required.
  7. Save your changes, if required.
