[AMBER] Units/Typos in MDL file format

Hi,
  Two issues tripped me up recently with regards to MDL format. I wonder if
we could clarify them in the AMBER manual.
First:
The "CHG" Flag says:

%FLAG CHG
%FORMAT(5e16.8)

REAL*8(NSITE) Partial charge for each solvent site (e).
 But I believe it has to be multiplied by 18.2223.

Also,

%FLAG LJSIGMA

%FORMAT(5e16.8)

REAL*8(NSITE) Lennard-Jones rmin/2(σ ∗/2) for each solvent site (Å). Note
that this is not σ .
 Can we rename this variable? Maybe LJRMIN. You could see how this could
cause problems.


-Dan
