A template for supplementary material in IEEEtran format

A template for supplementary material of the manuscripts in IEEE format (IEEEtran.cls) is not wrapped up for the IEEEtran. For my latest manuscript (which is still under review), I needed to put some graphs in the supplementary, so I could gather these hacks from the web. I gathered  all these HACKS couple of months ago, from different blogs, and sites for supplementary files of other journals. I could not find those blogs, so sorry for not providing reference.

I liked to change the section, figure, table, equation, citation numbering to include an additional S.  The following should be inserted into preamble.

% Hack For section headers starting with S 
\renewcommand{\thesection}{S.\Roman{section}} 
\renewcommand{\thesubsection}{\thesection.\Alph{subsection}}

To change the format of citations in the bibliography and the main text, a combination of natbib and IEEEtranN is needed

 
% Hack for citation command 
% use bibnumfmt to change style at the end of the document
\usepackage[numbers]{natbib}
\renewcommand{\bibnumfmt}[1]{[S#1]}
% citenumfont command adds S to all numbers
\renewcommand{\citenumfont}[1]{\textit{S#1}}

Numbering of the figures and table are done with

 
% Hack for making figures Say \figurename S\thefigure, e.g. Figure S1: 
\makeatletter 
\makeatletter \renewcommand{\fnum@figure} {\figurename~S\thefigure} 
\makeatother

 

 
% Hack for making tables Say \tablename S\thetable, e.g. Figure S1:
 \makeatletter
 \makeatletter \renewcommand{\fnum@table}
 {\tablename~S\thetable}
 \makeatother

 

And for the equations, we need the following

% Hack for making SOM Equations Conform to Science Format
% e.g. (S1), (S2), etc
\renewcommand{\theequation}{S\arabic{equation}}

A drawback of this method is that \eqref is not working, but \ref command still works pretty good. 🙂

I also find it handy to cross-reference labels between main and supplementary document. In the supplementary, we need to reference to the aux file of the main file, like:

 
\usepackage{xr}
\externaldocument{Main}
% where Main.tex is the main file of the manuscript.
