# how can I remove the institute from the author footline on beamer?

I'm using the Madrid theme. I have defined \institute as

\institute[]{\pgfuseimage{logo} \\ my-institute}


because I want the logo to appear at the title frame. Also, since all viewing the presentation are from the same institution, it makes no sense to declare the [] part of \institute. It seems redundant. But, in the footline, my name appears with an empty () to it's right.

My question is: how do I remove this ()? I don't want the institute specified at the footnote.

Just to be clear, my footline is something like:

my-name ()    |    title     |    date


I want it be

my-name   |    title     |    date

Madrid uses infolines as the outer theme, so you can set the footline template to not include the parentheses, but to keep all the other elements as they were:

\documentclass{beamer}

\makeatletter
\setbeamertemplate{footline}
{
\leavevmode%
\hbox{%
\end{beamercolorbox}%
\end{beamercolorbox}%
\end{beamercolorbox}}%
\vskip0pt%
}
\makeatother
\begin{document}

\author{A.U. Thor}
\institute{The Institute}

\begin{frame}
Test
\end{frame}

\end{document}


Here's the bottom of the frame produced by my example code:

Absent a MWE, here's one way you might modify the footline by customizing the outertheme. See p. 165 of the Beamer manual and tweak as needed to suit your needs:

\documentclass{beamer}
\useoutertheme[footline=authortitle]{miniframes}

\title{My awesome presentation}
\author{John Q. Public}
\date{17 November 2011}

\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}
\frametitle{Outline of Lecture}
\begin{itemize}
\item Background
\item Awesome results
\end{itemize}
\end{frame}

\end{document}
