[gmx-users] .gro file problem

[Albert]

hello:

  I finished a MD and it generate a .gro file: confout.gro

However, I find that there is some problems:

editconf -f confout.gro -o md.pdb

it said:

Program grompp, VERSION 4.5.5
Source code file: confio.c, line: 801

Fatal error:
Something is wrong in the coordinate formatting of file md.gro. Note 
that gro is fixed format (see the manual)

However, I can open it with VMD without no problem. But if I try to do 
it with gromacs, similiar errors happen.

grompp -f myMD.mdp -c md.gro -p complex.top -o md2.tpr
