# One column PDF from cas-dc two column class file

I am preparing a manuscript using Elsevier's cas-dc.cls class for two column output. I am looking for a way to produce a single column output PDF file using the cas-dc.cls for review.

The documentation for Elsevier LaTeX instructions are here and the CAS class documentation is here. I have gone through both but could not find a way to produce a single column output file using the cas-dc.cls class file. The documentation does not give details of the options that can be used with this class. It just tells that the class can be used as following:

\documentclass[<options>]{cas-dc}


However, no details of the options are given in the documentation.

I have also tried replacing cas-dc with cas-sc in the documentclass declaration of my LaTeX document, but this yields formatting problems.

Here is the MWE of what I am using:

\documentclass[a4paper,fleqn]{cas-dc}

\usepackage[numbers]{natbib}
\usepackage{lipsum}

\begin{document}
\let\WriteBookmarks\relax
\def\floatpagepagefraction{1}
\def\textpagefraction{.001}
\shorttitle{Leveraging social media news}

\title [mode = title]{This is a specimen $a_b$ title}
\begin{abstract}
Abstract goes here.
\end{abstract}
\maketitle
\section{Introduction}
\lipsum
\end{document}

• If I change cas-dc to cas-sc in your example, it works fine. Can you show an example that errors when you change to cas-sc? May 20 at 0:30
• @PhelypeOleinik, Code for the floats i.e. figures and tables creates problems and has to be changed. May 20 at 0:36
• Well, of course, if you change from double to single column the layout changes. But in your question you said there are errors, but I see none in your MWE. May 20 at 0:37
• The errors were due to some mistakes in the code which I have corrected. Now, there are only layout problems as you pointed out. I have edited my post to reflect this. May 25 at 6:37
• Okay, glad you found the errors. However your example shows no “formatting problems” (screenshot), so it's hard to give you any useful advice. Please post an example document that when compiled will show these problems. Also, you can't make single-column with cas-dc (dc stands for double column and sc for single column). May 25 at 12:40
