title: Why am I getting a zsh: exec format error?
body: <p>I am trying to run the metal executable from my zsh terminal in order to meta-analyze GWAS data. I have the executable in the correct directory and have checked that it is not 0MB due to truncation.</p>
  <p>Reproducible:
  Download the Linux file from <a href="http://csg.sph.umich.edu/abecasis/metal/download/" rel="noreferrer">http://csg.sph.umich.edu/abecasis/metal/download/</a></p>
  <p>In terminal:
  PATH TO EXECUTABLE ./metal
  zsh: exec format error: ./metal</p>
