    Hi Xiao,<br>
    <br>
    now I would try with providing the crystal symmetry information,

            if you run phenix.merging_statistics without giving it
            arguments it will print out available parameters that you
            can change. Among them are unit_cell and space_group.<br>
            <br>
            I'm guessing you can define them just like this<br>
            <br>
            unit_cell="10,20,30,90,90,90"<br>

                  Hi Phenixbb members,<br>
                  <br>
                  I am trying to use "phenix merging statistics" tool,
                  and I have an unmerged sca file from HKL2000,  because
                  the unmerged HKL2000 output does not have unit cell
                  information, so I also need to input a symmetry file,
                  how can I find the symmetry file? Is there a way to
                  generate a symmetry file?<br>
                  <br>
                  Thanks ahead.<br>
                  <br>
