After same struggle I managed to start r.denoise, but I received this strange message.
any idea?

r.denoise --verbose input=MDE_EM_UTM_WGS84@PERMANENT output=Denoised_MDE_EM_UTM_WGS84

r.denoise can’t read its own files?

Not sure -- maybe the above instructions are not enough. Please have a look
at the thread which Helmut K pointed (other post), and in the manual:

NOTES
r.denoise works with a cartesian coordinate system. Thus data in geographic
(lat-long) coordinates require projection during processing. The script is
able to do this if the EPSG code of a suitable coordinate system is provided.

As from the data names, they seem to projected in UTM. It should work! Maybe
specify, in addition an "epsg=EPSGofSomeProjection" for the region/country in
which you are working on?
Ah, and don't forget: RAM capacity of your system is, I guess, critical.
Please, let us know how it works.
Thank you, Nikos
