Hi Xiang, 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. phenix.angle model.pdb selection="chain A and resseq 1:123" selection="chain B and resseq 20:345" The underlying procedure would do the following: - extract two sets of coordinates of atoms corresponding to two provided atom selections; - draw two optimal lines (LS fit) passing through the above sets of coordinates; - compute and report angle between those two lines? Would this be helpful? Is it worth adding such tool? Pavel On 1/20/14, 5:48 AM, ?? wrote:
Hi,
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?
Thanks you very much for your help!
Sincerely, Xiang
