Masking interferograms before unwrapping

[esrivas17]

Hi dear developers,

A very short question. I am processing an area using ISCE-Mintpy. This area is quite hilly and has a lake in it, during the unwrapping all the area around the lake is affected by probably wrong values in the unwrapping. I only mask those pixels out later on in Mintpy, I would like to know whether there is a way to mask an area before unwrapping. Or what do you recommend in such cases?

Thanks in advance
