Subject: AMBER: No radius found for 2412 Zn Zn

Dear Amber-users

I performed MM-PBSA simulation and encounter some problem.
when I do >mm_pbsa.log
system give this info:
No radius found for 2412 Zn Zn

Then I modify "my_delphi.crg" and "my_delphi.siz" by adding Zn parameter, but this information still remain.

which file should I modify and what should I add?

Any suggestion would be very appreciated!

more my_delphi.crg
!Amber parm94 charges
N MET 1 0.1592
NA+ CIP 1.0000
CL- CIM -1.000
Zn Zn 2.000
C0 C0 2.000
(I added the last two lines

!my siz based on PARSE
Mg 0.99
Zn 1.10
C0 1.71

(beside Zn2+, there are also Ca2+ ions, so I also added C0 for Ca2+ ions)


Best regard!
