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


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


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.
