Re: [AMBER] query regarding the restart file of molecular dynamics simulation

After running the simulation, the restart file is now in binary cdf format.
So, do we need to convert the restart file in ASCII format and then submit
the further simulation. Or, do we need the changes in the production.in
file so that it will read the restart file in netcdf format, i.e, ntx=6
along with ntxo=0 and ioutfm=1
