Hi,
I am writing a macro which segments ROIA, and then segments things within
ROIA - I'll call them ROIA1, ROIA2. Likewise, I have a large ROIB and
within it, some small ROIs - ROIB1, ROIB2, ROIB3, etc. (there may be 400
large ROIs containing smaller ROIs within them)

I would like to be able to select all of the ROIs which are contained
within a certain ROI. How would I do that?

In Java, I would use a tree data structure for this type of search.

How would I do this in a macro? Searching the whole ROI list every time I
want to find a subset is time consuming.

Thanks,
Avital
