title: unable to access jarfile
body: <p>I ran a perl script in biotoolbox package.(http://code.google.com/p/biotoolbox/)
  but got the error message related with jarfile. </p>
  
  <pre><code>$./bar2wig.pl
  
   This program will convert bar files to a wig file
   Usage:
   bar2wig.pl [--options...] &lt;filename&gt;
  
    Options:
    --in &lt;filename&gt; or &lt;directory&gt;
    --out &lt;filename&gt; 
  
  $  ./bar2wig.pl --in  /Users/biotoolbox/scripts/ --out example
  
  This program will convert bar files to a wig file
  checking input file(s)....
  converting to gr files...
  Unable to access jarfile /usr/local/USeq/Apps/Bar2Gr
  writing wig file...
  cleaning up temp files... done
  </code></pre>
  
  <p>i am not sure what to do for the error: unable to access jarfile .
  it looks like java related error, although this script is perl.</p>
  
  <p>any comments for this?</p>
