[gmx-users] Problem in generation of tpr file

[Alex]

To be clear, I did suggest ignoring it _only_ if the warning is: a) 
understood, b) of known origin, and c) harmless. I am not sure what's 
your one case is when ignoring warnings is appropriate, but I routinely 
use '-maxwarn 10,' because I have a bunch of bonded parameters that 
override default stuff in ffbonded for DNA (I think this customization 
came from Tsjerk Wassenaar when we collaborated). The warnings appear 
even when no DNA is present in the system, but in either case I know 
exactly what I am doing.

In no way should new users interpret my suggestion as "it is okay to 
ignore grompp warnings." It is NOT okay to ignore them.
