Is that axis found by using a linear regression of some points that go through the center of the dimer and then is the direction of the axis found? <br><br>On Monday, April 3, 2017, Elaine Meng &lt;<a href="mailto:meng@cgl.ucsf.edu">meng@cgl.ucsf.edu</a>&gt; wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Matchmaker does not calculate the axis of symmetry, it superimposes the chains that you tell it to superimpose, as described in the link I sent earler. Then measure rotation figures out the axis and angle relationship between the two copies, also as described.<br>

&gt; Hi,<br>
&gt;<br>
&gt; I learnt that a dimer axis of symmetry is got by using matchmaker and then the rotation is measured from it. I would like to know the algorithm that is used to calculate the axis of symmetry and how exactly it is done if possible.<br>
&gt;<br>
&gt; Thank you.<br>
