[Users] Grid structure

Hi all,

I was wondering if someone could point me at how to parse the grid structure information in a Cactus output. I hope this is the right venue for this type of question.

In the output I'm examining, under the "Parameters and Global Attributes" node at root level, there's a "Grid Structure v5" dataset, which contains "grid_superstructure" and "grid_structure". Is parsing the string affiliated with the grid_superstructure component the best way of identifying the spatial extent, dimensions and refinement level of grids in the output?

Thanks very much for any pointers,

Matt
