Hi,
The simulation is still valid in this situation.
It is the equivalent of putting a smaller piece of tissue (e.g. a postmortem sample) into the scanner.
The simulation that you get is the same as if the specified region is the only object in the scanner.
All the best,
Mark

The runtime estimation of Possum decreases if those regions are removed from the input object. Does this really decrease the runtime and is the simulation still valid in this case?
