title: How to make bins with the size 100 for a start and end numbers using awk?
body: <p><strong>Input File 1</strong></p>
  
  <pre><code>NM_75 X + 3000623
  NM_47 X - 3000333
  NM_60 X + 3000132
  NM_70 X - 3000258
  </code></pre>
  
  <p>How to get the start and end coordinates at -1500 and +1500 for the each one in the 4th field and make bins with the size of 100 using awk?</p>
  
  <p><strong>output should be</strong></p>
  
  <pre><code>start coordinate -1500+3000623= 2999123
  end coordinate    3000623+1500= 3002123
  </code></pre>
  
  <p>now from the range of 2999123-3002123, have to make bins with the size 100 i.e., 3000/100 total 30 bins likewise for each other coordinates in the 4th field.</p>
