Hi,

            I am trying to incorporate Mn parameters using the following steps:

bsub -P Pan -app amber-mpich -Is -q interactive tleap -f leaprc.ff99SB

source leaprc.gaff

mods = loadAmberParams "frcmod.Mn" which I downloaded from http://www.pharmacy.manchester.ac.uk/bryce/amber#ion

Mn= loadpdb Mn.pdb (I saved the coordinates of Mn and protein separately in this file)

check Mn

FATAL: Atom .R<MN 303>.A<MN 1> does not have a type.
FATAL: Atom .R<MN 304>.A<MN 1> does not have a type.


The pdb file has only protein and MN atoms. Mn atom coordinates are as follows:
HETATM 1520 MG+ MG+ D 303 -14.664 -20.531 -22.254 1.00 59.85 MG2

Appreciate any help/suggestion in this regard.

Thanks and regards,
Latha.
