  <pre><code>IOError: [Errno 22] invalid mode ('wb') or filename: 'C:\\Users\\Viral Patel\\Documents\\GitHub\\3DPhotovoltaics\\Data_Output\\Simulation_Data\\Raw_Data\\Raw_Simulation_Data_2014-03-24 17:21:20.545000.csv'
  </code></pre>
  
  <p>I think it is due to the timestamp at the end of the filename. Any ideas?</p>
