Just for my info since I don't set properties. You mean that in the case of float you can have a nan or what is a "missing value"?

yes. Missing values are defined here: https://github.com/SpikeInterface/spikeinterface/blob/main/src/spikeinterface/core/base.py#L38

For ints and bool, we don't have missing values :)

cool thanks.
