title: removing double quotes from a file
body: <p>I have a tab delimited file, that looks like this.</p>
  
  <pre><code>"""chr1"    "38045559"  "38046059"  "C1orf122"""
  """"    ""  ""  "C1orf122"""
  """"    ""  ""  "YRDC"""
  """chr1"    "205291045" "205291545" "YOD1"""
  """chr1"    "1499717"   "1500625"   "SSU72"""
  </code></pre>
  
  <p>I got this file after converting a .csv to tab separated file from this command </p>
  
  <pre><code>perl -lpe 's/"/""/g; s/^|$/"/g; s/","/\t/g' &lt;test.csv&gt;test_tab
  </code></pre>
  
  <p>Now, I want my file to remain tab separated but all the extra quotes should be removed from the file. But at the same time when I print column 4 I should get all the names and for column 1,2, and 3 the co ordinates (this I still get it but with quotes).</p>
  
  <p>What manipulation shall I do in above command to do so, kindly guide.</p>
  
  <p>The output desired is (since I was asked to be clear)</p>
  
  <pre><code>chr1    38045559    38046059    C1orf122
                                  C1orf122
                                  YRDC
  chr1    205291045   205291545   YOD1
  chr1    1499717     1500625     SSU72
  </code></pre>
  
  <p>so that when I extract Column 4 I should get</p>
  
  <pre><code>    C1orf122
      C1orf122
      YRDC 
      YOD1
      SSU72
  </code></pre>
  
  <p>Thank you</p>
