[gmx-users] Input/Output error using grompp

[Stefano Meliga]

Hello,

I can't get rid of an error occurring using grommp:
-----------------------------------
Program grompp, VERSION 4.0.5
Source code file: futil.c, line: 330

File input/output error:
grompp.mdp
-----------------------------------

my command line is:

 >> grompp -r 4AKEpolHsol.gro -4AKEpolH.top -o 4AKEpolH.tpr -po 4AKEpolH.mdp

I am not giving any mdp file in input because I didn't run an simulation 
yet.
I want the preprocessed files .tpr and .mdp in output.

Can it be an issue related with my cpp pre-processor?


Thanks,

Stefano
