title: Convert .gprobs files from Impute2 to PLINK format
body: <p>I have some imputed .gprobs files (one per chromosome), imputed by Impute2 downloaded from dbGaP, and I need to convert this file into .bed format of PLINK in order to do some analysis.</p>
  
  <p>My .gprobs files look like:</p>
  
  <pre><code>--- rs371609562:61395:CTT:C 61395 CTT C 0 0.023 0.977 0 0.039 0.961 0 0.015 0.985 0 0.026 0.974 0 0 1 0 0 1 0 0 1
  </code></pre>
  
  <p>Could someone help me find out how convert this kind of file into PLINK format? Or guide me about which files I need to perform the convertion?</p>
  
  <p>P.D.: I know that this question maybe shouldn't be here, but I didn't know any other place to ask about it.</p>
