Dear Amber users,
I am using MM_PBSA module in amber9 for calculating the Free binding energy
of a complex (Protein + Inhibitor) using the following input file..
Input:
.GENERAL
PREFIX snapshot
PATH ./
COMPLEX 1
RECEPTOR 1
LIGAND 1
COMPT ./actcdk2_complex.top
RECPT ./actcdk2_receptor.top
LIGPT ./h717_ligand.top
GC 0
AS 0
DC 0
MM 1
GB 1
PB 1
MS 1
NM 0
.PB
PROC 2
REFE 0
INDI 1.0
EXDI 80.0
SCALE 2
LINIT 1000
PRBRAD 1.4
ISTRNG 0.0
RADIOPT 0
NPOPT 1
SURFTEN 0.00542
SURFOFF 0.92
.MM
DIELC 1.0
.GB
IGB 2
GBSA 1
SALTCON 0.00
EXTDIEL 80.0
INTDIEL 1.0
SURFTEN 0.0072
SURFOFF 0.00
.MS
PROBE 0.0
.PROGRAMS
While running the script i got the fallowing error message..
Script: mm_pbsa.pl binding_energy.mmpbsa >binding_energy.log

Kindly some one suggests me how to solve it.
Thanks in advance.
