    <div class="m_-4788251956048260825moz-cite-prefix">Hi Sam,<br>
      <br>
      Thank you very much for your re-organization.<br>
      <br>
      I have a quick question. How can we track the previous branch
      revision changes after your re-organization?<br>
      Recently, Weiyu has some problems with running WAM-IPE after he
      made some changes to the WAM Z(height) calculation. Some of us are
      discussing to identify which versions of the code he used. For
      example, Weiyu&#39;s version was the revision number 90097 of the
      previous WAM-IPE_NEMS201606 branch. How can we do svn diff
      module_MEDIATOR_SpaceWeather.<wbr>F90 between his branch version and
      the latest version of the trunk(90371)? Does this work?<br>
      <br>
      $ svn diff -r 90097:90371 module_MEDIATOR_SpaceWeather.<wbr>F90<br>
      <br>
      Thanks.<br>
      <br>
      Regards,<br>
