[gmx-users] grompp not recognizing mdp file parameters

[toma0052]

Hello,
     It seems that I am having a problem in that grompp is not recognizing
the parameters that I enter into an mdp file, nor is it recognizing the text
in the .top file.  When I run a simulation, the output that I get is as
follows:

Program grompp, VERSION 3.3.1
Source code file: grompp.c, line: 448

Fatal error:
number of coordinates in coordinate file (area_1.03_1.gro, 17365)
             does not match topology (dppc.top, 0)
-------------------------------------------------------

     What could be the problem here?  Is this just some simple formatting
error that I've missed?  I have run simulations before, and everything seemed
to work out fine.  The run above is simply the same files from the successful
simulation copied into a new directory with a few alterations made to the mdp
file.  If my other files still run, why are essentially the same files not
recognized when put into a new directory?

Thanks,
Mike
