<div dir="ltr">Apologies for sending it directly to you. I was able to figure out the problem though. I had created an alias named <i>angle </i>due to which whenever I ran the <i>angle </i>command, the alias would run instead of the built-in <i>angle </i>command. I deleted that alias and created a new one with a different name & now everything is working fine.<div><br></div><div>Thanks again for your help</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Jan 8, 2023 at 10:53 PM Elaine Meng <<a href="mailto:meng@cgl.ucsf.edu">meng@cgl.ucsf.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi Prathvi,<br>
Please send chimera questions to <a href="mailto:chimera-users@cgl.ucsf.edu" target="_blank">chimera-users@cgl.ucsf.edu</a> instead of my individual address. Otherwise, your question may fall through the cracks and not get any answers.<br>

This all works fine for me in Chimera 1.16 release, e.g. commands:<br>
<br>
open 5fzp<br>
define plane :252.B & aromatic ring<br>
define plane :261.B & aromatic ring<br>
angle p1 p2<br>
<br>
...then the Reply Log contains:<br>
<br>
0, chain A: DAIP<br>
#0, chain B: DAIP<br>
5fzp opened<br>
plane name, ID, center, normal, radius: plane: p1 ( 46.248, 56.206, 31.842) ( 0.547, -0.816, 0.186) 1.399<br>
plane name, ID, center, normal, radius: plane: p2 ( 46.861, 61.257, 27.361) ( 0.280, 0.020, -0.960) 1.403<br>
Angle between p1 and p2 is 87.643<br>
<br>
I don't know which part you did wrong.<br>

If you are using ChimeraX then you cannot specify the plane by something like p1 but instead you need the model number. In Chimera, that command works fine for me.<br>
