title: Change string word order in a file
body: <p>I have a file with this kind of strings:</p>
  
  <pre><code>gene_1  1   181 +   1   01  15.2689 b   -   -   -
  gene_2  220 300 -   0   01  0.649993    b   -   -   -
  gene_1  1   295 -   0   10  16.1465 b   -   -   -
  gene_1  39  278 +   0   11  13.4122 b   28  33  -0.698805
  gene_1  1   133 -   0   10  13.9421 p   139 144 0.493777
  </code></pre>
  
  <p>I need to change the fourth column (the column with + and -) within the fifth (0 and 1) to obtain the next:</p>
  
  <pre><code>gene_1  1   181 1   +   01  15.2689 b   -   -   -
  gene_2  220 300 0   -   01  0.649993    b   -   -   -
  gene_1  1   295 0   -   10  16.1465 b   -   -   -
  gene_1  39  278 0   +   11  13.4122 b   28  33  -0.698805
  gene_1  1   133 0   -   10  13.9421 p   139 144 0.493777
  </code></pre>
  
  <p>any ideas?</p>
