Here is the classad attribute structure you need for transferring your output back from the remote globus machine to specific files on your condor-g job broker/universal client. By default, the output goes to your cluster's spool directory. The example below shows how to move these to /tmp/ on the condor host.
Note that TransferOutput files are separated by commas, and TransferOutputRemaps files are separated by semicolons.
The trick as usual is to get the condor true-names for the parameters you want to use. These are typically NOT the familiar names from condor_submit. Always create a command script for what you want to do before writing your birdbath api code, and then use condor_q -l to see the internal names that condor actually uses. These are the ones you will need to use in your classAdStructAttr array.
