title: Can't execute FastX Toolkit on Mac
body: <p>I downloaded the FastX toolkit precomplied binaries for &quot;MacOS X 10.5.8 (32-bit)&quot; (<a href="http://hannonlab.cshl.edu/fastx_toolkit/download.html" rel="nofollow noreferrer">http://hannonlab.cshl.edu/fastx_toolkit/download.html</a>). However, when I cd into the directory with the tools and try to execute any of them (e.g. with any command like fastq_quality_filter -h), I get the error:</p>
  <p>-bash: /usr/local/bin/fastq_quality_filter: cannot execute binary file</p>
  <p>I'm not positive but it seems like it might be because the file kinds are &quot;Unix executable&quot; which might not be compatible with Mac (though I downloaded the binaries that were supposedly for Mac). I've tried chmod + x but the files already have execution permission so that didn't help. Any other ideas?</p>
