title: Tesseract tsv output not working
body: <p>I'm trying to execute tesseract from command line in Ubuntu 17.10. I want the output in a <code>.tsv</code> file because I need the confidence rate. As explained <a href="https://github.com/tesseract-ocr/tesseract/wiki/Command-Line-Usage#tsv-output-currently-available-in-305-dev-in-master-branch-on-github" rel="nofollow noreferrer">here</a>, I execute:</p>
  
  <pre><code>tesseract testing_img.png out tsv
  </code></pre>
  
  <p>but I'm getting the following error:</p>
  
  <pre><code>read_params_file: Can't open tsv
  Tesseract Open Source OCR Engine v3.05.00 with Leptonica
  </code></pre>
  
  <p>and the output is written correctly in a <code>out.txt</code> file. It seems that it reads that <code>tsv</code> parameter as a file to read, but I don't know why.</p>
  
  <p>I've compiled Tesseract from source because I need Tesseract 3.05 in order to have a <code>.tsv</code> file as output, so I can't use the version in the Ubuntu repository because it has Tesseract 3.04.</p>
  
  <p>I'm running Ubuntu 17.10.</p>
  
  <p>Here's some information about my Tesseract installation:</p>
  
  <pre><code>$ tesseract --version
      tesseract 3.05.00
       leptonica-1.75.3
        libpng 1.6.34 : zlib 1.2.11
  
  $ ls /usr/share/tesseract-ocr/tessdata/
      configs  eng.traineddata  ita.traineddata  osd.traineddata  pdf.ttf  tessconfigs
  
  $ echo $TESSDATA_PREFIX
      /usr/share/tesseract-ocr/
  </code></pre>
