Autosegmental Representation with pst-asr

Question

I am using Texmaker and MiKTeX to try and produce an autosegmental representation such as the one in this image:

The following code is given in John Frampton's pst-asr user's guide:

\asr[xgap=2em,syB=2.5em] hwari|
\@(1,sy){L}
    \-[xed=true,xedratio=.4](1,ts)\-[style=dotted](2,ts)
\@(2,sy){H}
    \-(2,sy)(2,ts)
\@(4,sy){L}
    \-(4,ts)
\endasr

No matter how I build the PDF document, the result is similar to this (i.e. not the autosegmental representation above):

I am very new to this, so it is likely I am making a simple error. Any assistance would be greatly appreciated.

See also the full code of my document:

\documentclass[10pt,a4paper]{article}
\usepackage{pst-asr}
\begin{document}
\asr[xgap=2em,syB=2.5em] hwari|
\@(1,sy){L}
    \-[xed=true,xedratio=.4](1,ts)\-[style=dotted](2,ts)
\@(2,sy){H}
    \-(2,sy)(2,ts)
\@(4,sy){L}
    \-(4,ts)
\endasr
\end{document}

Thank you.

The pst-asr documentation is somewhat difficult to read. In order to use the shortcuts \@ and \- you need to first execute the \tiershortcuts command. Following Stefano's comment, I've put this into a \psset command to apply it to each asr environment, which will ensure that the shortcuts don't interfere with any other packages' commands. Furthermore, the style=dotted should be linestyle=dotted. So the complete document should be:

\documentclass[10pt,a4paper]{article} 
\usepackage{pst-asr}
\psset{everyasr=\tiershortcuts}
\begin{document}
\asr[xgap=2em,syB=2.5em] hwari|
\@(1,sy){L}
    \-[xed=true,xedratio=.4](1,ts)\-[linestyle=dotted](2,ts)
\@(2,sy){H}
    \-(2,sy)(2,ts)
\@(4,sy){L}
    \-(4,ts)
\endasr
\end{document}
