[gmx-users] x2top - is it just me?

[Eviatar Tron]

hi all,
I am trying to run x2top on .gro files I created
from genbox by the command:
genbox -cp wedge.gro -ci wedge.gro -o 12wedge.gro -nmol 11 -box 30 30 1

I am doing this because I want to see the interactions between
12 molecules of this wedge. 
now, this creates a fine .gro file, but if i want to run grompp
on it I also need a topolgoy file

there is a -p option to genbox for a .top file which is supposed 
to be both input and output - I didnt understand how this could
be, but anyway it won't create me a new .top file - just complain
if it doesnt exist, so I guess this is not really an output option.

so the thing to do is probably x2top on the .gro file,
but I cant get it to work - it just gets stuck after reporting
the number of type to mass conversions and atom 40.
I didn't think it should take long, and 10 minutes seems more
then enough.
 
I also tried PRODRG, which is actually what created the wedge.gro
file, but it didnt read the 12wedge.gro file

I am trying simple carbon molecules, which, I admit,
are not textbook examples of how carbon behaves,
but I shouldnt think this is the problem

can anyone help?
	thanks
