Hi Dr. Case,
I tried running the AMBER advanced tutorial A2 with the NMA file, and I
receive the same error message. I've tried Googling the error but nothing
relevant came up. I'm not sure what MPI I'm using. I'm running AMBER 9 on
a Linux machine via ssh to the SDSC Teragrid machine, and I don't know if
the MPI can be changed through that.
Thanks,
Lili
