[Tex/LaTex] Affiliation of author in achemso class

achemsotitles

I use the achemso class in order to write a scientific article. I have to set author and their affiliation with affiliation or altaffiliation commands. Here is a short example :

\documentclass{achemso}

\title{Title}

\author{Author 1}
\affiliation{lab 1}
\author{Author 2}
\email{author@lab}
\author{Author 3}
\author{Author 4}
\affiliation{lab 2}

\date{\today}

\begin{document}

\end{document}

output :

enter image description here

I would like author 1 to belong to lab 1 and lab 2 and other author to belong only to lab 2. But it does not work. With the above example author 1 belongs only to lab 1.

If I add an \altaffiliation command for lab 2 just after author 1 it works but lab 2 appears two times at the bottom of the page.

enter image description here

How can I avoid that achemso write two times the same affiliation ?

Best Answer

You need the \alsoaffiliation command, which deals with this case:

\documentclass{achemso}

\title{Title}

\author{Author 1}
\affiliation{lab 1}
\alsoaffiliation{lab 2}
\author{Author 2}
\email{author@lab}
\author{Author 3}
\author{Author 4}
\affiliation{lab 2}

\date{\today}

\begin{document}

\end{document}

\altaffiliation is intended for the case where you have a specific note or similar for one or more authors, whereas \alsoaffiliation is used for 'standard' affiliations which are shared in some way.
