Did you use xleap to make ryou parm file ?
In that case, you cannot use M for bacbone definition as xleap doesn't
create this parameter (see in your parm if you have somewhere bla bla
...).
The more recent versions of leap add the chain types. The
current version can be downloaded from the amber web.
