Re: [PyMOL] Drawing chain to visualize backbone

Hi Jared, yes your method works as you described, it does NOT follow every turn. I'm sorry, I was mistaken. Your method is very good, however I wanted do simplify it even more, and showing a very rough course of the protein. I ended up with a pdb file consisting of only 27 amino acid residues (wh

Hi Simon - Glad you figured out a method that worked for you. However, I'm wondering why you ended up with "un-smoothed" helices using the `cartoon_smooth_loops` method. Are you sure you typed the last two commands in my example correctly (`alter` and `rebuild`)? I'm getting a single, relati

Hi Carlos and Jared, thanks for your answers! Jared, your method is quick to do, but the ribbon follows every turn of a helix, which I wanted do avoid. Carlos, your method did what I wanted. I commented out amino acids which c-alphas I did not want to be included, and ran the script zero_residues.

Hi Simon - I don't think you need to do any deleting of atoms at all--there are a few settings that will be helpful here. Here's how I would do what I think you're asking for: # load and set basic representation load structure.pdb as cartoon # create the smooth version create smooth, structu

ecule. (Or else I didn't understand what you want to do). There is also a command  > set ribbon_transparency  that might do what you want, but I never used it myself. Carlos From: Simon Schweizer (schwei...@tum.de) Sent: Thursday, November 14, 2013 02:41 PM To: pymol-users@lists.sourceforge.ne

[PyMOL] Drawing chain to visualize backbone

2013-11-14 Thread Simon Schweizer
Dear all, I have a complex protein (with a knot in the polypeptide chain) and want to show the rough course of the chain, so everyone can easily see that there is a knot inside. I don't know how to draw such a complex 3D object in a drawing program, so I want to do that in PyMol (or another simil
