Hi Bruno, can you post the standard output at initialization time? From
the configuration file that you used, you do not have the wellTempered
option on: therefore, I'm not sure how the weight could change.

If you are indeed observing Gaussians with variable height given your
configuration, then please report also the code version you are using.
