[Tex/LaTex] beamerposter – merge two columns at the end of the poster

beamerbeamerpostercolumns

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}

[Tex/LaTex] Beamerposter… Columns not all aligned at top

Since beamerposter style is based on beamer, the columns' options are also inherited from beamer. Hence, simply copy/pasting for convenience from the manual, below are these alignment options for

\begin{columns}[option]
...
\end{columns}

∙ b will cause the bottom lines of the columns to be vertically aligned.

∙ c will cause the columns to be centered vertically relative to each other. Default, unless the global option t is used.

∙ onlytextwidth is the same as totalwidth=\textwidth.

∙ t will cause the first lines of the columns to be aligned. Default if global option t is used.

∙ T is similar to the t option, but T aligns the tops of the first lines while t aligns the so-called baselines of the first lines. If strange things seem to happen in conjunction with the t option (for example if a graphic suddenly “drops down” with the t option instead of “going up,”), try using this option instead.

∙ totalwidth=⟨width⟩ will cause the columns to occupy not the whole page width, but only ⟨width⟩, all told.

[Tex/LaTex] centering block body with respect to block title in beamer

You could use something like this:

\documentclass{beamer}

\newlength\bodywd
\setlength\bodywd{.95\linewidth}

\setbeamercolor{block title}{fg=olive,bg=olive!20}
\setbeamercolor{block body}{fg=blue,bg=blue!20}

\setbeamertemplate{block begin}{%
 \vskip.75ex%
 \begin{beamercolorbox}[rounded=true,leftskip=1cm,colsep*=.75ex]{block title}%
  \usebeamerfont*{block title}\insertblocktitle%
  \end{beamercolorbox}%
  \vskip.5ex %
  \usebeamerfont{block body}%
  \hspace*{.5\dimexpr\linewidth-\bodywd\relax}%
  \begin{beamercolorbox}[wd=\bodywd,colsep*=.75ex,sep=.75ex,vmode]{block body}%
}
\setbeamertemplate{block end}{%
  \end{beamercolorbox}%
\hfill\null%
}

\begin{document}

\begin{frame}
\begin{block}{The Title}
text
\end{block}
\end{frame}

\end{document}

enter image description here

The idea is to keep the width of body block in an auxiliar length \bodywd and to add, before the block, a horizontal space given by 0.5(\linewidth-\bodywd).
