LEaP: The parm and coord files disagree on the number of atoms

 I'm trying to run a FEP calculation with gibbs, and I get an error
message telling me that the parm and coord files disagree on the number
of atoms.
 The leap commands employed are here. (The unit c6x was in the library
units2.lib)

source leaprc.ff99
loadoff units2.lib
loadamberparams c6x.par
solvatebox c6x WATBOX216 10.0
saveamberparm c6x 100c6x.top 100c6x.crd

 As I got the top and crd file in the same command, how it's possible
they have different number of atoms?

 The gibbs error message is displayed at the end of message.


 Thak you in advance,


Miguel.
