[gmx-users] problem by start with grompp

[Alexej Mazheika]

Dear all!

I'm new with Gromacs.
I prepared some job for it but I cann't start with grompp. It writes me
"Fatal error:
Something is wrong in the coordinate formatting of file conf.gro. Note that
gro is fixed format (see the manual)".
What is wrong? I want to calculate a silver cluster contining 125 atoms.
And the conf.gro file was prepared according to on-line manual of Gromacs.
Corresponding input-files are attached here.

Thank you in advance,
Alex
