Hi Xiang,<br>
<br>
there is no ready-to-use tool for this right now, but I can spend a
few moments and add one so it's available in next Phenix nightly
build in a day or two.<br>
<br>
phenix.angle model.pdb selection="chain A and resseq 1:123"
selection="chain B and resseq 20:345"<br>
<br>
The underlying procedure would do the following:<br>
- extract two sets of coordinates of atoms corresponding to two
provided atom selections;<br>
- draw two optimal lines (LS fit) passing through the above sets
of coordinates;<br>
- compute and report angle between those two lines?<br>
<br>
Would this be helpful? Is it worth adding such tool?<br>
<br>

<div>I have a DNA model which is composed of two DNA duplexes. I
want to measure the angle between the two duplexes and if
there a way to do it in PHENIX or in other software?</div>

<div>Thanks you very much for your help!</div>
