      I was mentioning about OPLSAA force field for ATP <br>

      procedure to be followed and some guidance from<br>

    The link you mentioned, and links from it contain all the
    readily-available information. For ATP, you may well find a
    validated topology in the published literature.<br>

          All force fields are different, and since you haven't said
          which one you're trying to use there's nothing that anyone can
          tell you. &nbsp;Read the primary literature for the force field you
          want to use and follow the procedure laid out therein.<br>
