Dear Amber users,
I am trying to use amb2gmx.pl with Ambertools (Amber14). When I used Amber11, I had no problem in this step, however, with Ambertools (Amber14) it complains about rdparm.

amb2gmx.pl --prmtop receptor.top --crd receptor.crd --outname receptor_gmx
| New format PARM file being parsed.
| Version = 1.000 Date = 12/04/14 Time = 12:15:16
 WARNING: ATOMIC_NUMBER NOT FOUND IN NEW PRMTOP
          Atomic element col.78 left blank in pdb.
          You can use Parmed to add atomic_number.
sh: 1: /opt/amber14/bin/rdparm: not found
(...)
    Error: pdb and rdparm disagree on number of atoms!

The problem is that rdparm is not found. Surprisingly, when I look for rdparm in /opt/amber14/bin/rdparm, I cannot find it. I have read that in Amber 14 rdparm had been replaced by cppptraj. Is this correct? How could I make amb2gmx.pl work without rdparm?

Thanks a lot for your help in advance!!

Best wishes,

Rebeca.
