​Hey Tsjerk! So good to connect again here! ​I will look up Mole plugin for possible channels, come back and write here again and a script would of course be very nice to have. Thanks for the help. Kanika On Thu, Jan 26, 2017 at 10:39 PM, Tsjerk Wassenaar wrote: > Hi Kanika, > > That's been qui

Thanks Jared. First part, is perfect. So pseudo atom lies between nitrogen atoms. Second part, I don't have specific xyz coordinates because it is centre of a tunnel in the protein and that's the struggle. On Thu, Jan 26, 2017 at 10:01 PM, Sampson, Jared M. < jms2...@cumc.columbia.edu> wrote: >

Hi, For your 2nd question: You can make pseudoatom at Center of mass or center of geometry (for an object or probably selection too) using the following script: https://pymolwiki.org/index.php/Center_of_mass In your case you mat try: import center_of_mass com SelectionObjectName, state=1#Create

Hi Kanika - You can get more information on the wiki: https://pymolwiki.org/index.php/Pseudoatom. To answer your specific questions, to make a pseudoatom between the two terminal Ns of Arg 100 on chain A of myobj: ``` pseudoatom my_ps1, myobj and chain A and resi 100 and name NH1+NH2 ``` and

Dear PyMol Users, I am struggling here two things. 1). I want to place a pseudoatom in the charge centre of a non aromatic residue, like arginine. 2). Is it possible to place another pseudoatom in the centre of a cavity in the protein? I am thinking how can I define the co ordinates of the positio
