Another question about the ROI manager, which is a very powerfull yet poorly documented feature of ImageJ :

- what is the exact operation performed by "Combine" and "Split" when selecting multiple ROIs in the ROI manager ?

- In a stack, is the ROI added to the ROI manager related to the slice from where it has been added? If I do "Select" such a ROI in the manager, either manually or programmaticaly, will it recall just the ROI or will it jump also to the slices from where the ROI has been defined ? It seems to be the case, at least when done manually.

- what is exactly the way the ROI manager remembers on which slice is the ROI located ? It seems to have something to do with it's default name. If I "Add" a ROI from slice 2 of my stack, rename the ROI, and select it back it does'nt remember the slice anymore. So if I want to keep the link between the ROI and it's slice, I can't rename the ROI ? Or should I just keep the first stretch of digits (which seem to actually reflect the slice number) ?
