Hi Hanno,

Thanks for your reply. We are still wandering in the code to get the
reason of this failure of the 'assert' . We cant even figure out
whether the cause for the failure is in the module Acquisition itself
or not.

Can you say whether the failure is in the module Acquisition??

If not can you help us in figuring out the reason of this failure?
