How to center author name and affiliations?

Question

my current code is as below:

\documentclass[fleqn,11pt]{wlscirep}
\usepackage{authblk}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{fourier} 
\usepackage{array}
\usepackage{makecell}
\usepackage{lipsum}


\title{\centering cccccc}
\author{xxxx}
\affil{vvvvv}
\affil{vvvvv}

and it is appearing as below

How do i make the author name and the affiliation details to appear in the middle below the title instead? thank you.

Answer 1

This is fixed in the class definition file. However, you can change the format. The command that produces the titles is \@maketitle. It contains the command \raggedright two times, once for the title and once for the author information. Replacing each instance by \centering produces the required result. This can be achieve by patching the command as follows

\usepackage{etoolbox}

\makeatletter
\patchcmd{\@maketitle}{\raggedright}{\centering}{}{}
\patchcmd{\@maketitle}{\raggedright}{\centering}{}{}
\makeatother

\documentclass[fleqn,11pt]{wlscirep}
\usepackage{authblk}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{fourier}
\usepackage{array}
\usepackage{makecell}
\usepackage{lipsum}
\usepackage{etoolbox}

\makeatletter
\patchcmd{\@maketitle}{\raggedright}{\centering}{}{}
\patchcmd{\@maketitle}{\raggedright}{\centering}{}{}
\makeatother

\begin{document}
\title{cccccc}
\author{xxxx}
\affil{vvvvv}
\affil{vvvvv}
\begin{abstract}
  x
\end{abstract}
\maketitle
\end{document}
