I am trying to do MMPBSA calculation using script

mpirun -np 4 $AMBERHOME/bin/ -O -i -o FINAL_RESULTS_MMPBSA.out -sp PRMT7_WT_NH1.prmtop -cp complex.prmtop -rp receptor.prmtop -lp peptide.prmtop -y *.crd

But I am getting an error which I am unable to solve it

Error: *.crd matches no files.
  File "/nethome/axt651/apps/amber14/bin/", line 103, in <module>
  File "/nethome/axt651/apps/amber14/lib/python2.7/site-packages/MMPBSA_mods/", line 156, in file_setup

TrajError: /nethome/axt651/apps/amber14/bin/cpptraj failed when querying *.crd
Error occured on rank 0.
Exiting. All files have been retained.
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

I have cross checked is correctly installed in amber home directory
Kindly help me out.

thanking you,
