Create groups (trees, cells…) to check them separately in the various viewers and data extractors.

• New group: specify its name
• Existing group: modify the group name if needed

• Choose the type of the group elements (trees, cells…)

• A static group retains only the ids of the elements selected at group creation time
• A dynamic group retains the rules defined at group creation time and rerun them at each invocation

Use the filter manager to build your group.
