How could I export the interferometric phase to a file so I can process it with Matlab

Hi everyone,
I have done the coregistration using SLC data of Sentinel-1 and the interferometric phase is obtained.

Now I want to export the subset of the phase to do some subsquent operations with Matlab. The question is how could I export the phase to a file, so I could process the exact same phase in Matlab. Should I export it as GeoTiff?

The tif image doesn’t seem to be good enough.
Thanks in advance!

Hi @Cook,
Did you find out how to export properly the output of SNAP to matlab ?
I am trying with TIFF or GAMMA but have some issues with the width and lenght of the output in matlab
