Looks like the same problem. As Ben pointed out, you need to pass profile.run() an executable
(e.g. the main() function itself) and not something that's already been
executed. Since you've already called main(seedFile), it's the return value
that is being passed to profile.run(), and that's why it's complaining...

Perhaps you meant:
profile.run('main(seedFile)', '/Data/tmp/whatever')

?

your hint and REREADING THE DOCUMENTATION made me realize it
was the QUOTE MARKS on the function call i was missing:

profile.run('main(seedFile)','profileOutFile')

Harit, perhaps this was your problem, too?

Ben, thanks for your help.
