The \not rendering and the line over sigma symbol

Question

I am writing a paper and I need to use the \not command on \sigma which stands for a order relation on a set. The issue is that the line over the sigma symbol is rendered poorly, is there any way I am not aware of so that the exact symbol I need is displayed correctly?

Please add a minimal working example (MWE) that illustrates your problem. You can draw it in detexify for both checking the symbol and also having a snapshot of what you wanted to post here. — percusse, Nov 10 '12 at 15:25
@tohecz it's how my professor "named" the order relation, there isn't any I can do about it. — haunted85, Nov 10 '12 at 15:35
@percusse tried to edit the post, but the site throws me back a server error, but I'll keep in mind for next questions I might ask, thank you. — haunted85, Nov 10 '12 at 15:36

You can use centernot:

enter image description here

\documentclass{article}
\usepackage{centernot}% http://ctan.org/pkg/centernot
\begin{document}
$\not\sigma\ \centernot\sigma$
\end{document}
