# eliminate the space between multiple numeric citations - bioinfo.cls

I have a document that is using natbib via the following requirepackage command in bioinfo.cls line 827.

\RequirePackage[numbers,sort&compress]{natbib}

When I cite multiple papers using the cite command, I get spaces between each of the numbers. For example, the following citation:

\cite{dinnes2007systematic,pai2009novel}

Gives me the following in-text output:

[3, 4] However, I would like it to read:

[3,4] Is there a way to accomplish this?

I tried this solution

How to eliminate the space between multiple numeric citations when using citep and natbib?

But it does not work with bioinfo.cls. Any help would appreciated.

• I'm not sure why you'd like to have wrong output. The space after a comma is mandatory. – egreg May 31 '16 at 7:46

use

\documentclass[numbers,sort@compress]{bioinfo}
\makeatletter
\def\NAT@def@citea{\def\@citea{\NAT@separator}}%
\makeatother
\begin{document}
...
\cite{dinnes2007systematic,pai2009novel}
\bibliographystyle{plainnat}
\bibliography{...}

\end{document}
