Dear Phenix users,<br><br>I try to refine a big complex at low resolution. I am a little confused about the syntax of using torsion angels gradient-driven refinement. Is it now the default for individual sites refinement instead of  cartesian ? If not, should I add :  sites.Torsion_angles=all for example ? Could you shed some light on this,<br>
<br>Thank you,<br clear="all"><br>-- <br>Peter<br>
