1. Data
Kunsu wrote code to produce NPE trees, including event header, single electron and pair branches. He went through the structure, cuts, size and CPU for tree production. We discussed about pairMass and pairDCA cuts. It was suggested to use pairDCA cut of 1 cm, and study the pairMass cut in embedding by Xiaozhi.

2. Simulation
We discussed how Xiaozhi should start the simulation study. The first step is to get EvtGen installed and running on RCF. Xiaozhi will work on it.
