Hey Francesca,
Now there's a small bug in the program. Sorry about it. We'll put the
fixed version on in a bit. The problem arises because you don't
specify the secondary structure and pymol is not yet available for
doing so. The workaround is to explicitly set the secondary structure
to loop, by adding "-ss LLL" on the command line. Thanks for pointing
that out.
By the way, you might want to post these issues on the Martini forum:
http://md.chem.rug.nl/cgmartini/index.php/user-platform/forum
It's not exactly Gromacs...
Cheers,
Tsjerk
