Hi Austin,

The issue with the crash is that you need in ``patTupleProduction.py`` the ``Utilities.chain_sequence`` [1] function is called to set in the input tags to the previous sequence items output tags.  It assumes that the input should be named the standard "src", not "inputPatElectronsTag" (rage).

I will modify the cfg_chainer and send you a PR with instructions.

Evan
