[Mristudio-users] ROI sequence in the binary map

[susumu mori]

Hi Yuan,

Yes, the first one has to be OR. Otherwise, you can't initiate a tracking.
I think your question can be simplified as;

> suppose you have two ROIs, say A and B
> if you set ROI A first, it becomes "OR" and B becomes "AND"
> if you set ROI B first, it becomes "OR" and A becomes "AND"
> question is, whether these two results are different or not.
This is a good question. I assume these should be the same. Have you seen
difference in this kind of simple cases?
