Dear Amber List,
We have recently install amber 11 and ambertools1.5 on our Linux cluster. The Calculation of the binding free energy of a protein-ligand complex was a success , but when I am running the MMPBSA decomposition calculation ,then I got error message during parse GB output files!(below). I don't know where is it going wrong. Any help would be appreciated. and I have attached the final results file as well as the run files.
The input file for mmpbsa:
Per-residue GB and PB decomposition
&general
endframe=50, verbose=1, interval=5,
/
&pb
istrng=0.100,
/
&gb
igb=5, saltcon=0.150,
/
&decomp
idecomp=2, dec_verbose=3,print_res="71; 83; 204; 202; 475; 476"
/
Then I submit my job :
mpirun -np $NP MMPBSA.MPI -O -i mmpbsa_per_res_decomp.in -o FINAL_RESULTS_MMPBSA.dat -do FINAL_DECOMP_MMPBSA.dat -sp complex_solvated.prmtop -cp complex.prmtop -rp rp.prmtop -lp M6A.prmtop -y *.crd > progress.log 2>&1
The program stops after giving this error message:

I don't know where is it going wrong. Any help would be appreciated.
