Hello Professor, thank you very much for your answer.
Professor, as you answered, my problem is here.
In this tutorial, she pointed to the "Identify regions with colors" option, which can solve my problem, and reduce the number of areas, such as the example (right figure), which is exactly what I need.
But I can not find this option in my brainstorming toolbar.
How can I reduce the Destrieux Atlas, which has 148 scouts that I can now see on my system, like the example above, and show me the exact image to the right of the example above?
Of course, I do not have the "Identify regions with colors" option.
