+\begin{frame}{Introduction}
+  \begin{itemize}
+    \item Our goal is to study \textbf{seeding} for the \textbf{offline} GSF tracking with the \textbf{new pixel detector}.
+    \item Specifically, we want to optimize the window sizes used in the new pixel-matching scheme already implemented in HLT.
+    \item Since last update\footnote{https://indico.cern.ch/event/662743/contributions/2744847/attachments/1534642/2403597/main.pdf},
+    \begin{itemize}
+        \item Migrated Code from \texttt{9\_0\_2} to \texttt{9\_2\_8}
+        \item Integrated the new pixel matching into the trackingNtuple. (although still a work-in-progress)
+        \item Regenerated \texttt{trackingNtuple}s for dataset \\

+        $\texttt{highEt} + \min(0,\texttt{Et}-\texttt{highEtThreshold})*\texttt{lowEtGradient}$.
+      \item For the first hit, these parameters for the $\delta \phi$ window are,
+        \begin{itemize}
+          \item $\texttt{highEt}=0.05$
+          \item $\texttt{highEtThreshold}=20$
