Dear Everyone,

I'm a newcomer for Amber software. I installed Amber8.0 on SGI machine and
launch it. When I launch sander program, there're some errors below:

lib-4324 : UNRECOVERABLE library error

Encountered during a namelist READ from unit 5
Fortran unit 5 is connected to a sequential formatted text file: ""
IOT Trap
MPI: MPI_COMM_WORLD rank 0 has terminated without calling MPI_Finalize()
MPI: Received signal 6

[1] Exit 1 mpirun -np 4 sander -O -i -p -c hepta-water.crd -r ...

My input is:

mpirun -np 4 sander -O -i -p -c hepta-water.crd -r
hepta-water.rst -o min.out & is below:

molecular dynamics run

Would you kindly tell me what's the problem and how to solve it? Thanks in
