there was a compilation problem, or a library missing i don't know, but
i've tried on another machine and it works.

it's was i was trying to do, but isn't so easy!
Have you noticed the fourth column in the prep section where the atoms
type and positions are defined?
That one full of "M","E","S","B" or "" ?
That's the real issue, because it's a local definition of the topology
and changing the order you change the whole topology...
Anyway, the .mol2 thing worked... so problem solved
Thank you all
