Allocating Variables to a Raster

Variables can be allocated to one or more rasters. You can allocate rasters manually for single measure variables or in the predefined or preselected rasters for an entire device or a container.

Note
You can only assign measurement variables to a raster. To allocate a variable to multiple rasters, the option Enable multiple rasters must be activated in the User Options (see also User Options for Measurements: General Tab).

Note

You can only assign measurement variables to a raster.

To allocate a variable to multiple rasters, the option Enable multiple rasters must be activated in the User Options (see also User Options for Measurements: General Tab).

In the Variables pane of the Variables tab, the visualization of the raster options are as follows:

	Preselected Raster	Preselected rasters are rasters which the user can preselect in the Raster Preselection dialog box. You can only preselect the raster when the checkbox Use Predefined Rasters in the Source pane is disabled.
	Selected variable	Indicates that the user selected the measure variable in a raster.
	Partly selected variable	Valid only for special cases, for example, measurement arrays. Some measurement array elements are selected in this raster. To display a detailed raster selection of the measurement array, see Displaying the Raster of a Measurement Array.
	Predefined Raster	Predefined rasters are rasters which an A2L project optionally defines for a variable. Predefined rasters are used when the checkbox Use Predefined Rasters in the Source pane is enabled.
	Selected variable in predefined raster	Indicates that the user selected the measure variable in a predifined raster.
	Partly selected variable in predefined raster	Valid only for special cases, for example, measurement arrays. Some measurement array elements are selected in this predefined raster. To display a detailed raster selection of the measurement array, see Displaying the Raster of a Measurement Array.
	LAB file raster	Indicates that the raster is defined in the selected LAB file.
	Not selected	Indicates that the user did not select a measure variable in a raster.

To allocate a raster to a variable:

Click on the raster corresponding to the variable in the raster matrix.
Note
If the raster matrix is not displayed, activate it as described in Configuring the Representation of Variables View. If you have not selected a raster, INCA uses the predefined raster.
The corresponding variables are selected automatically according to the raster allocation. Undo the last selection by selecting the corresponding variable with a left mouse click or by re-selecting it with the context menu command Deselect.
If you click on a measure variable raster field in a predefined raster , the selected raster symbol appears. To indicate whether a measure variable in a predefined raster was already selected, the predefined raster symbol now remains displayed next to the selected raster symbol.

Note
If the raster matrix is not displayed, activate it as described in Configuring the Representation of Variables View. If you have not selected a raster, INCA uses the predefined raster.

To change a raster preselection:

Use the raster preselection to allocate all variables of a device or a container to one or more rasters at the same time.

In the Sources pane, disable the option Use Predefined Raster.
In the Variables pane, select the measure variables for which the raster shall be changed.
Use the Left arrow key on your keyboard to jump to the desired raster field.
Press Ctrl + space bar to assign or reassign the preselected rasters.
or
Open the dialog box Raster Preselection with the command Open Raster Preselection in the Sources pane or with the keyboard command Alt+r or via the context menu.
Mark one or more rasters to be allocated for all variables of the device you have selected.
The raster preselection is identified by in the raster matrix of the Raster Preselection dialog box.

Note
The option Use Predefined Raster resets the variables to the default raster defined in the A2L file.

To allocate a raster of calculated signals:

Calculated signals can only be allocated to the virtual raster resulting from the algorithm. After a calculated signal is added to an experiment, the raster allocation cannot be changed in the variables selection dialog box.

To allocate a raster of a measurement array:

In the Variables pane, click the corresponding raster matrix of the measurement array.
All measurement array elements are selected.
