Graphics, Figures & Tables ⇒ Best way to refer to equation in another .tex file

[gammapoint]

Hi, I have two files, one main article .tex file and another supplementary material .tex file. In the main file I have some equations defined with \label associated with them. I'd like to be able to use \ref{eq:whatever} in my supplementary material *.tex file.

Is this possible? If not, is there an easy way for me to simply define in my supplementary material tex file what number I want \ref to refer to and that way I just need to update the equation numbers manually at the top of the document once rather than over and over again throughout the document?

Hi,

for references to external files, you could use the xr package.

That looks absolutely perfect. Thanks so much!
