[PyMOL] Coloring c-alpha atoms makes cartoons colored too

Hi everyone, I want to color C-alpha atoms of a selection in a specified colour (red) and and the cartoon representation in a separate color(grey). When i try colouring the calpha's in red, the same color leaks onto to the cartoon representation also, making it look grey with patches of red.

[PyMOL] How to make outlines to spheres drawn in PyMOL ?

Dear users, I was interested in knowing if there is an option or setting in PyMOL which is able to make an outline to spheres. I am aware of the show spheres command and have used it extensively to show C-alpha atoms of amino acids as spheres. I am curious to know how I could make an outline

[PyMOL] About ray trace and spheres

Hi, I am representing C-alpha atoms of binding site as spheres. I am using the set sphere_mode command to adjust the radius of the spheres. I use the sphere_mode as 4. However, when I do a ray tracing, no matter how small the spheres I set, they appear very large once the ray tracing is carried

[PyMOL] selecting atoms around a ligand in a protein structure

Hi Pymol-users, I need to select only the atoms [and NOT complete amino acid residues] which are lying in a radius of 4.5 Angstroms from the ligand from a ligand-bound protein structure. I am aware that the command: select site, br. resn FAD and chain A and resi 45 around 4.5 and not HET

[PyMOL] Having problem running: findSurfaceResidues.py

Hi Pymol Users, I was trying to use the findSurfaceResidues.py script listed on PyMOLwiki (http://www.pymolwiki.org/index.php/FindSurfaceResidues), to find out which residues which are present on the surface of the protein. These are the steps I have followed: 1) Made a file called

[PyMOL] FInd the number of residues within a selection

Hello, I wanted to know what is the command-line syntax for finding out the number of residues which fall within a selection made in PyMOL. Once the selection is made, the command line shows the number of atoms selected, but I wanted to know the number of residues present in such subsequent

[PyMOL] finding complete residues within a RANGE OF distance cutoff

Hello , I want to extract out complete amino acid residues which fall within a radius of 4 to 9 Angstroms from the ligand. What do I do in such a case, given the pdb id's, chain ID, the name of the ligand and its residue id? PS: I want to avoid, extracting out cmplete residues within a 0-4.5A
