    Hi,<br>
    <br>
    looking through <br>
<a class="moz-txt-link-freetext" href="http://sourceforge.net/p/cctbx/code/HEAD/tree/trunk/mmtbx/refinement/minimization.py">http://sourceforge.net/p/cctbx/code/HEAD/tree/trunk/mmtbx/refinement/minimization.py</a><br>

    <br>
    Is weight_xray_chem.py code that could move to cctbx?
    (cctbx_project/mmtbx/refinement/weight_xray_chem.py)<br>
    <br>
    Are there other cross dependencies?<br>
