Hi Emily,

I downloaded the latest integration
build of STEM, installed the latest Java 8 update, and tested the integration
build on my mac.
The known bug re: the eclipse launder on mac is still
unresolved to I opened the package contents, command-click on STEM, and
I was able to run stem successfully.
After stopping and restarting STEM, I
installed into the new workspace the Global
Geographic Models, the Mexico
USA pandemic flu scenario, and the Automated
Experiment Example

We did migrate to a new build server so I wanted to check
the build of STEMs build in geographic data is still ok. I could view the
global models in the designer perspective. I could run the USA/Mexico scenarios,
and I could run the AutomatedExperiment scenario. I then
opened the Experiments folder and I was able to run the AutomaticExperiment.automaticexperiment
target.


In the error log you sent I'm seeing
the message
        Unable
to load content for resource platform:/plugin/org.eclipse.stem.data.geography/resources/data/country/ste/ste_:_area.graph
this is an unusual exception. Our built
in data for countries uses the three letter country code so I would expect
the letters STE to represent the three letter code for a country but there
is no country with the code STE, and STEM has not built in data with that
code.
The usual syntax by the convention (iso
3166)  used in STEM (e.g., for the united states) is:

USA_0 indicates the country USA at admin
level 0 where 0 is the country level code
USA_1 indicates the country USA at admin
level 1 where 1 is the STATE level code
USA_2 indicates the country USA at admin
level 2 where 1 is the COUNTY level code

STEM allows users to build a graph with
containment edges (eg, counties inside states, inside countries) in which
case the computation is only computed at the lowest administrative level
(eg counties in that example) and results can roll up the hierarchy.

Could you please zip up the project
you created (in your workspace folder) and send it to us? I suspect you
created a custom graph so I'm not sure why STEM is looking in the /data/country
path for data. The _:_ symbol seems to indicate a problem. 
Perhaps you created a flat square latttice
graph  ? 

fyi I also tested the command line options
for running STEM headless and that also worked fine for me on my mac. Perhaps
you could join a future STEM call and we could help to sort out that issue
as well.
