Subject: RE: [AMBER] Problem reading PDB file into XLEAP - SLEAP

Drs. Case and Zhang, a little further detailed checking shows that
my AMBERHOME environment variable is correct, but in repeating the
tests of sleap I find that an error occurs whenever I use *any*
environment variable within the program. In fact, the parameter
files are loaded correctly whenever I spell out the path in detail.

Thus, this is not a real problem. Thank you both for your efforts
to help me arrive at a solution.

Works for me. Is your AMBERHOME environment variable set correctly?
Wei: sleap should probably print out the search path when emitting an
error message like the one above.

This is probably the same search path problem as above. And, I don't
see this behavior, so you might make sure you have the latest version of
sleap (AmberTools 1.2), if the AMBERHOME variable is not the problem.
