Actually the first problem that I had was: when I had tried to run a
simulation using a normal restart file (.rst) the following message was
shown in the output file:
| Flags: MPI
getting box info from netcdf restart file
| NetCDF restart box info found
|Largest sphere to fit in unit cell has radius = 0.000
ASSERTion 'e' failed in ew_setup.F90 at line 306.
When I did what Dan said, use cpptraj to add box lengths in the restart
file, I got this message:
| Flags: MPI
getting new box info from bottom of inpcrd
| INFO: Old style inpcrd file read
ERROR: I could not find the number of atoms or the time on
the second line of your inpcrd file [New_2NPT.rst]. Bad INPCRD file!
When I specify the restart format (trajout New_2NPT.rst restart) in the
cpptraj input file I have this message:
| Flags: MPI
getting new box info from bottom of inpcrd
| INFO: Old style inpcrd file read
| peek_ewald_inpcrd: Box info not found in inpcrd
I hope I have been clear
