I don't quite see why this 2022-question is attached to the 2010-question. Am I misreading it, or aren't they separate issues? The first one was about voxel dimension, and this one is about matrix size---those are likely separate considerations.
It would also be helpful/necessary to see the exact commands being run to be able to consider what is happening. In general, a question about unexpected behavior of a command should include the command being run.
