3.2. Managing groups of fields (experiments)

To work with groups of fields, use the commands in the "Group" menu.

3.2.1. Viewing groups

To view groups, click the Group>View group command. This will open the "View group data" dialog box (Fig. 3.2.1.1).

The "Group list" column contains groups and the "Group Fields" column shows fields available for the selected group. The information about the number of groups and the total number of unique fields in the project is displayed at the top of the dialog box. Below the columns, you can see information about the selected group: group name, the number of fields in this group, and the data type. Click "OK" to close the dialog box.

3.2.2. Adding a new group

To add new groups to the project, click the Group>Add group command. This will open the "Edit group data" dialog box (Fig. 3.2.2.1).

To create a new group, do the following:

  1. Select field types by clicking the radio buttons in the "Select field types" pane. The fields of the selected type will appear in the "Data fields" list. Click the "Add" button to add fields to a group or the "Remove" button to remove fields from a group.
  2. Enter the name of the group (for example, NewGroup0) into the "Group Name" field. If the "Simultaneously add 'inverted' group" box is checked, the two groups, NewGroup and INV_NewGroup, will be added to the list (the INV_NewGroup group includes fields missing in the NewGroup group).
  3. Click "OK". To cancel the operation, click "Cancel". If a group with the same name already exists, you will see the "Error" dialog box (Fig. 3.2.2.2) where you will be asked to rename the group you have created.

After clicking "OK", you will see the "Edit group data" dialog box (Fig. 3.2.3.2) from where you can edit the following group parameters:

  1. The list of fields included into a group (displayed in the "Group fields" list). Click "Add" to add fields to a group or "Remove" to remove fields from a group.
  2. Group name. You can edit the name of the group in the "Group Name" field.
  3. Add "inverted" group that will contain all fields from the "Data fields" list. The name of the "inverted" group will have the "INV_" prefix. To add an inverted group, check the "Simultaneously add 'inverted' group" checkbox. If an "inverted" group with this name already exists, the fields in this group will be updated according to the last changes you made.

Click "OK" to apply changes and close the dialog box and "Cancel" to cancel changes and close the dialog box.

3.2.4. Deleting a group

Click the Group>Delete group command to open the "Delete field group" dialog box used to delete a group from the current project (see Fig. 3.2.4.1). To delete groups, selected these groups in the list and click "Delete". To cancel the operation, click "Cancel". The total number of groups is displayed above the group list. Figure 3.2.4.1 shows that the NewGroup0 group is selected for deleting.
