This does not provide nearly enough information for us to help.

What version of Amber are you using? Which program is this? (sander or
pmemd?) Programs typically do not terminate without printing _something_
to standard error. Look at the standard output and error streams when you
run the program for any hint of an error message (even if it makes no sense
and looks like gibberish). Are you sure that the program finished? Are
you running the *exact* B1 tutorial files?
