I realize this - after all, I wrote the code :-)

I recommended using cpptraj instead of ambpdb as a way to debug what
is going on. By design, ambpdb with the cpptraj backend suppresses all
non-error messages (i.e. warnings, general information, etc). When
using cpptraj you can see if say hold1.rst is in another format
recognizable by cpptraj; if the format cannot be detected then maybe
the file itself is just corrupted.
