I am back :(

The procedure i did

1) do_dssp -s test-Struc.pdb -f test-Struc.pdb -dt 1 -o ss.xpm
The menu appears I choose 5 (Main Chain) and I obtained the following message 
--------

Back Off! I just backed up ddsGGvys to ./#ddsGGvys.1#

The ddsGGvys is indeed a pdb file with the protein atoms (main chain). But the program seems to run because the prompt did not appear but the ouput ss.xpm is never present. 

What is the problem ?

Thank you

What error?  It appears that do_dssp is backing up an old intermediate file that
gets generated as part of the calculation.

Unless someone has already developed them, you'll have to do it yourself (not an
easy task).  See here:

I solved the problem.
I found one more "ffgmx.itp" in my pro.itp.

Dear gromca users,

I'm a new user of gromacs.
I'm trying to run energy minimization on the system of a short peptide and a
lipid bilayer.
The following is my top file.

++++++++++++++++++++
;
#include "ffgmx.itp"
#include "../lipid.popc.itp"
#include "popc.itp"
#include "pro.itp"
#include "ions.itp"
#include "spc.itp"


[ system ]
; name
Fusion peptide on POPC

[ molecules ]
; name  number
Protein 1
POPC    128
Na      2
SOL     3655
+++++++++++++++++++



And I copied em.mdp with a little modification from the tutorial.

cpp                 =  cpp
define              =  -DPOSRES
constraints         =  none
integrator          =  steep
nsteps              =  100
;
;   Energy minimizing stuff
;
emtol               =  2000
emstep              =  0.01

nstcomm             =  1
ns_type             =  grid
rlist               =  1
rcoulomb            =  1.0
rvdw                =  1.0
Tcoupl              =  no
Pcoupl              =  no
gen_vel             =  no
++++++++++++++++++


After runing grompp I've got the following error message.


++++++++++++++++++++++
Program grompp, VERSION 3.3.1
Source code file: topio.c, line: 388

Fatal error:
Invalid order for directive defaults, file
""/panfs/storage.local/scs/home/myunggi/gromacs-openmpi/share/gromacs/top/ffgmx.itp"",
line 4
++++++++++++++++++++

I think I have only one [ defaults ] section.
Does Anybody have an idea? What is wrong?

Have a great day.
