I came across (but not examined) messages complaining about
antechamber in amber10 (amber tools 1.0). If present complaining is a
duplication of such messages, please forget about it.

I am dealing with pyrazine compounds, where antechamber in amber10

not fully investigated the issue as I am in a hurry, though, changing
to amber9, no error message and the prepin file is a valid file.

Notice that generation of the pdb file was with the same package that
I have always used with success with respect to antechamber. In
particular, the atom types were correct for the force fields used (MMX
