Try this:

>SetupPanoramix (or SetupBender See if the code works with other projects)

>python

Once in Python, do the following:

>>>from LHCbConfig import *

>>>import GaudiPython as gaudi

>>>import gaudigadgets

>>>appMgr = gaudi.AppMgr()

>>>sel = appMgr.evtsel()

>>>sel.open(['PFN:~/path/to/myDSTfile.dst'])

>>>evt = appMgr.evtsvc()

>>>appMgr.run(1)

>>>evt.dump()

>>>evt.ls()

What did we do?

We opened python, imporeted some useful modules, then ran AppMgr().
After that, we used the the event service (evtsvc)
Using this we let appMgr run over 1 event
Then we dumped the event information
Finally, you can literally ls through the directories to see what's there. For instance, if you are running MC, try
>>>evt.ls('/Event/AllStreams/Phys')

Helpful? Email me if you have any comments.


NB: if you get stuck trying to figure out what's going on, try dir(evt), or just dir() what you don't understand.
