The default output for restart files was changed in amber16, to netcdf format.
If you wish to get the old format, set ntxo=1.

Of courese, if you are using Amber16, you should also use AmberTools16. The
ambpdb program can accept netcdf restart files, using the "-c" flag.

Not without more information. At a minimum, we would need to know the exact
symptoms, i.e. what input did you give to VMD, and what messages did it emit?
Nothing has changed about trajectory files in Amber for a very long time.
We recommend that you use ioutfm=1 to get netcdf format for trajectories:
there are many reasons for this, and VMD understands them fine. Are
you sure VMD knows how to gunzip the old formatted files internally?
Suggestion: use cpptraj to examine your trajectory file, making sure it
seems to be OK and have the expected number of frames. Try VMD with the
unzipped file.
