I can't make an octree with more than one subdivision

I have a point cloud with 100,000 points, and when I run Edit --> Octree --> Compute, I always end up with a single 8-box structure around my cloud. It sounds like I can recursively make finer resolution, from looking at web documents, however I can't see how to do that from within the GUI. I'm using v2.7.0, 64-bits. Is there a secret to accomplishing this?
thanks!

CloudCompare builds the octree whenever it needs it.
This method is only used to force the computation and display the octree. Once you have done so, you have to select the 'octree' entity in the DB tree (should appear below the cloud). Then you can change the currently displayed level in the 'octree' entity properties (as well as the way it is displayed).

AHA! I love it, thanks!!! Now for my next ignorant question...is there a way to output this octree/segmentation to a file to use in another code? That is, can I save the hierarchy of the tree, the cubes axes, and the points that are in each cube?
