I am using this template to create a poster with beamerposter. I am trying to create a two-column poster, with the references occupying both columns at the end.

Here's my try. Basically what I did was to create first a huge one-column-wide poster, split it up in two for a while, and then re-merge it again right in the end. However, I can't understand why it doesn't work:

\documentclass[final, 20pt]{beamer}

\usepackage[size=a0, scale=1.5]{beamerposter} % Use the beamerposter package for laying out the poster

\usepackage{array, multirow, hhline}

\usetheme{confposter} % Use the confposter theme supplied with this template

\setbeamercolor{block title}{fg=ngreen,bg=white} % Colors of the block titles
\setbeamercolor{block body}{fg=black,bg=white} % Colors of the body of blocks
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70} % Colors of the highlighted block titles
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10} % Colors of the body of highlighted blocks
% Many more colors are available for use in beamerthemeconfposter.sty

%-----------------------------------------------------------
% Define the column widths and overall poster size
% To set effective sepwid, onecolwid and twocolwid values, first choose how many columns you want and how much separation you want between columns
% In this template, the separation width chosen is 0.024 of the paper width and a 4-column layout
% onecolwid should therefore be (1-(# of columns+1)*sepwid)/# of columns e.g. (1-(4+1)*0.024)/4 = 0.22
% Set twocolwid to be (2*onecolwid)+sepwid = 0.464
% Set threecolwid to be (3*onecolwid)+2*sepwid = 0.708

\newlength{\sepwid}
\newlength{\onecolwid}
\newlength{\twocolwid}
\setlength{\paperwidth}{48in} % A0 width: 46.8in
\setlength{\paperheight}{96in} % A0 height: 33.1in
\setlength{\sepwid}{0.024\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.464\paperwidth}
\setlength{\twocolwid}{0.952\paperwidth}
\setlength{\topmargin}{-0.5in} % Reduce the top margin size

Any idea as to why the section References doesn't show up at all?

I was unable to compile the non-minimal example from your question (error File ended while scanning use of \@xdblarg.) and being so far from a minimal I did not want to debug, but basically you can just close the columns environment and continue after wards with normal text.

\documentclass[final, 20pt]{beamer}

\usepackage[size=a0, scale=1.5]{beamerposter}
\usepackage{lipsum}

\setlength{\topmargin}{0.5in} % Reduce the top margin size
\setlength{\parskip}{3em}

\begin{document}

\begin{frame}[t]

\begin{columns}[onlytextwidth]
    \begin{column}{.45\textwidth}
        \lipsum[2]
    \end{column}
    \begin{column}{.45\textwidth}
        \lipsum[2]
    \end{column}
\end{columns}

\lipsum[2]

\end{frame} 

\end{document}

  • That did the trick. I was thinking of it as much more complicated! Thanks! – RobertP. Sep 23 '17 at 20:56
