title: get channel name with nptdms
body: <p>I use a npTDMS package (<a href="http://nptdms.readthedocs.org/en/latest/" rel="nofollow">http://nptdms.readthedocs.org/en/latest/</a>) for reading .TDMS files.
  The problem is that I want to get channel data with the syntax:</p>
  
  <pre><code>from nptdms import TdmsFile
  tdms_file = TdmsFile("path_to_file.tdms")
  channel = tdms_file.object('Group', 'Channel1')
  </code></pre>
  
  <p>As I understand I can also get the data with:</p>
  
  <pre><code>TdmsFile.channel_data('Group', 'Channel1')
  </code></pre>
  
  <p>I can get the 'Chanel1' with:</p>
  
  <pre><code>TdmsFile.group_channels(group)
  </code></pre>
  
  <p>But this returns:</p>
  
  <pre><code>[&lt;TdmsObject with path /'name_of_the_group'/'name_of_the_channel'&gt;]
  </code></pre>
  
  <p>The question7problem is: how can I get only</p>
  
  <p>name_of_the_channel</p>
  
  <p>from the above output?</p>
