RE: Getting UrbanSim up and Running

Zak,

I have inserted some comments in line, below.

This is a bug in our code. Trying to create your own Opus package as
described in Section 10.2 of the Opus Manual causes a problem. Thanks
for letting us know, and my apologies for the error. We have unit tests
for this, but clearly they don't cover this case. I'll let you know
when the code is fixed.

Some of the unit tests require a baseyear database. Unfortunately, we
do not have permission to distribute the test database that we use
(which is simply a tiny part of our PSRC database). This means that
some of the tests will fail if you do not have access permissions to our
database server (which you don't).

We plan to fix this by replacing our PSRC-subset with a subset of the
Springfield-Eugene database that we are updating to work with Opus. I
hope this will be ready sometime this autumn. Until then, please
disregard any error messages that complain about not being able to
access our database server.

I believe this is the same problem as mentioned above, since
'psrc_2000_baseyear_fircrest' is the subset of our PSRC database that we
use for testing. If you were trying to run a simulation with your own
database, then please let me know what you are trying to do and I'll try
to help.

If you have more questions, please feel free to contact me directly.
