title: Converting multiple radar files with Py-ART
body: <p>So, i'm trying to write a script to convert multiple radar files in a directory using Py-ART.</p>
  
  <pre><code>import sys
  import glob
  import os.path
  import pyart
  
  list_of_files = glob.glob('*.mvol')
  
  for file in list_of_files:
      print(file)
  
      radar = pyart.aux_io.read_gamic(file)
  
      pyart.io.write_cfradial( file + '.nc' , radar, format='NETCDF4')
  </code></pre>
  
  <p>The code actually works, but instead of converting multiple files, it just converts the first one.</p>
  
  <p>I know it's an issue with the loop but i don't know what I'm missing.</p>
