[gmx-users] Fatal error:Atom index (1) in settles out of bounds (1-0)

[willting]

Hi,
  I added ffamber_v3.3.1 to gromacs-3.3.1 and wanted to use the AMBER99 Wang protein/nucleic acid forcefield.
  Run the commands:
pdb2gmx -ignh -f sev.pdb -o sev.gro -p sev.top -missing -water spc
editconf -bt cubic -f sev.gro -o sev_box.gro -c -d 1
genbox -cp sev_box.gro -cs -p sev.top -o sev_water.gro
grompp -v -f em.mdp -c sev.gro -p sev.top -o sev_em.tpr
 
  then it showed:
 
-------------------------------------------------------
Program grompp, VERSION 3.3.1
Source code file: toppush.c, line: 1108
 
Fatal error:
[ file "/usr/local/gromacs/share/gromacs/top/spc.itp", line 41 ]:
Atom index (1) in settles out of bounds (1-0)
-------------------------------------------------------
what should I do ?
 
Thanks,
 
will
