Dear Amber user,
I am facing problem to get binding energy residue wise using decomp option.
My system contains one DNA and a dendrimer. And the problem is arising due
to this dendrimer molecule. The input file is following
.GENERAL

PATH
/home/bnandy/dna_dendrimer/workspace/65_s1_g4/mm_pbsa/decomp/

.MS
PROBE 0.0
SANDER $AMBERHOME/exe/sander
.PROGRAMS
And the error message is
"Missing TGB for GB in 1 (residue 77)"
In my case ligand is the dendrimer and the receptor is the DNA. All the
input files and the residue numbering seems to be ok. Searching the
archive I couldn't find the solution. Can someone please help me.
Many thanks
Bidisha
