When generating my LaTeX document (RevTex 4.1) using TeXShop on Mac OSX 10.10.3 the document generates a rather ugly line above my references but below the section heading.

This is the code I am using to generate my references:
\documentclass[%
reprint,
amsmath,amssymb,
aps,
floatfix,
]{revtex4-1}
\usepackage{graphicx}% Include figure files
\usepackage{dcolumn}% Align table columns on decimal point
\usepackage{bm}% bold math
\usepackage{gensymb} %symbols eg. \degree
\usepackage[numbered]{Files/mcode} %Allow import of MATLAB code
\begin{document}
%References
\clearpage %Put references on separate page
\onecolumngrid %Make references entire page
\section{References}
\bibliography{Files/Bibliography.bib} %"bibliography" -> bibliography file name
\end{document}
Any help is removing this line or getting a prettier line would be much appreciated!
\documentclass{...}, the required\usepackage's,\begin{document}, and\end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Null May 21 '15 at 00:59\section{References}anyway. – Mico May 21 '15 at 01:50
