title: How can I run clustalw using Biopython
body: <p>I am using windows 7. I have installed python 2.7 and Biopython 1.57. I created the following script:</p>
  
  <pre><code>from Bio.Clustalw import MultipleAlignCL 
  cl = MultipleAlignCL("myseqs.fasta") 
  print("Command line: %s"%cl) 
  clpath="C:\Program Files\ClustalW2\clustalw2.exe" 
  cl = MultipleAlignCL("myseqs.fasta",command=clpath) 
  
  from Bio.Clustalw import do_alignment align = do_alignment(cl) 
  </code></pre>
  
  <p>But I got an error message.</p>
