The OPERA experiment is designed to perform first direct observation
of $nu_{tau}$ appearance in an almost pure $nu_{mu}$ beam. The
OPERA detector is a hybrid set-up which combines a lead/emulsion
target with various electronic detectors. It is located in Gran
Sasso Laboratory (LNGS), 730 km away from CERN where neutrino beam
is produced. A good electron identification in the ECC brick would
also allow OPERA to search for $nu_{mu}rightarrownu_{e}$
oscillations. We have studied electron identification in the
Emulsion Cloud Chamber (ECC) brick which was exposed to CERN SPS H4
electron beam. Emulsion scanning was performed in LNGS scanning
laboratory. FEDRA framework was used for the data analysis. In
total, we have found 30 electron showers in the brick. The
characteristics of each shower have been studied. The background
base-track contamination in the shower was estimated as $20pm 4$.
This is mainly due to shower overlap of electrons and passing
through cosmic rays.
