Good afternoon!

I'm trying to run a simulation using LES with noe restraints. I have
prepared topology and coordinate files for LES, restraints for LES. But an
error occurs when reading the topology file:

* NOT FOUND **%**FLAG BOND_FORCE_CONSTANT*

But it's definitely in our file:
….

   17474 17477 17480 17483

*%FLAG BOND_FORCE_CONSTANT*

%FORMAT(5E16.8)

  0.34000000E+03 0.34000000E+03 0.43400000E+03 0.36700000E+03
0.36700000E+03

  0.34000000E+03 0.34000000E+03 0.34000000E+03 0.55300000E+03
0.43400000E+03

  0.36700000E+03 0.36700000E+03 0.36700000E+03 0.36700000E+03
0.36700000E+03



%FLAG BOND_EQUIL_VALUE

%FORMAT(5E16.8)


We tried different topology file formats (.top, .parm, .prmtop, .parm7), it
didn't help.

We also tried sander.LES.MPI and just sander.LES, but it still doesn't
work.

What could be the problem?

Thanks a lot!
