[Pw_forum] coordination system for polarizations in matdyn.modes

[lfhuang]

Hello everyone:
   Could anyone tell me what the coordination system for the polarizations (epsilon) of vibrating atoms is in the output 
file matdyn.modes of matdyn.x? Is it Cartesian coordination(I guess so)? or lattice coordination?
 
I'd like to appreciate any help!

Best Wishes!

Yours Sincerely
L.F.Huang
