When I look at the log file, leap load all parameters correctly
including terminal map.
However, I've got the following error message.
+++++++++++++++++++++++++++++++++++++++++++++
Created a new atom named: OXT within residue: .R<ALA 392>
One sided connection. Residue: TP3 missing connect0 atom.
total atoms in file: 1520
Leap added 1410 missing atoms according to residue templates:
1410 H / lone pairs
The file contained 1 atoms not in residue templates

WARNING: There is a bond of 25.854368 angstroms between:
------- .R<ALA 392>.A<C 9> and .R<FE2 393>.A<FE2 1>
ERROR: The unperturbed charge of the unit: -2.972900 is not integral.
WARNING: The unperturbed charge of the unit: -2.972900 is not zero.
FATAL: Atom .R<ALA 392>.A<OXT 11> does not have a type.

Quit
++++++++++++++++++++++++++++++++++
Leap can't assign ALA to CALA, and complain missing type of OXT.
Does someone have any idea?
