set cartoon_side_chain_helper is an easy way, in cartoon mode, to only show the side chain of a residue. Now select the Display menu at the top of the page and select the sequence option. At this stage you may just see the bound ligand as a tiny molecule – one bound to each polypeptide chain. How do you select a ligand in PyMOL?ĭisplay the molecule within PyMOL and use the Preset>Pretty mode to create a ribbon diagram. How do I get a white background? In version 0.61 or later, simply use the bg_color command. How do I make the background white in PyMOL? You can also save images using the “Save Image” option in the “File” menu. This format is directly readable by PowerPoint, and can be easily converted into other formats using a package like ImageMagick. How do I export an image from PyMOL?Īll images (ray-traced or not) can be saved in PNG format using the “png” command. Lastly, just do File→Save Image As→PNG to save your high resolution image. So, the exact command to type into PyMOL would be, ray 1600, 1200. Which command or tool is used for high definition image in PyMOL? If you computer is doing fine on memory, choose the highest memory setting to make the picture. Additionally you can go to Setting –> Rendering –> Antialias (Real time) –> SMAA. Choose the highest antialiazing settings you have. Rebuilds the molecular structure to the highest quality (lowest performance). How do I get high quality images from PyMOL?

Calculate the distance between sulphur and c-alpha atoms of cysteines that take part in disulphide bridges using the “measurement” wizard.Action -> generate -> vacuum electrostatics -> protein contact potentials Then, try setting.Show everything as surface, show the antigen (resname is IN, look for it in the sequence) in sticks, red.Show everything in grey, H3 in red, any residues in a 4Å range from H3 in dark red - hint: select H3_around, byres( H3 around 4).Show all aromatic residues as spheres - hint: select aromatic, resname tyr+phe+his+trp.Show everything as cartoons, L chain in red, H chain in blue.
Generate 1 HQ ray tracing for all the following points tab-completion works: for example, if you writeĪnd press tab, PyMOL will complete “cartoon”.play with transparencies (especially with surfaces).use set antialias, 2 (sets a higher antialias, images are smoother).use set ray_trace_mode, 1 (draws a small black outline).You can save the image from the “File” menu or by writing Hint: if your computer takes too much time to do this, try rendering a smaller area, to hide objects outside of the rendering area or not interesting and to use ray with a given size of the image: The following selection identifier exist:Ĭhange the background to white and create a rendering: You can change the representation of a selection like this Resi 90-103 = any residue between 90 and 103Ĭhain H and resi 90-103 = residue between 90 and 103 in chain HĬhain H or resi 90-103 = any residue between 90 and 103, whole chain H The selection uses Boolean logic, but be careful: Now the selection is on the right menu as well. The protein sequence should now be visible. There are, close to each molecule/selection, 5 buttons:Ĭlick the “S” button at the bottom-right of the viewer window. The same can be done in the right menu of the viewer window. Try mouse -> 2 button view,then use CTRL + move Move the structure using your mouse/touchpad.

This command sometimes fails randomly, in this case download the file from the PDB database and open it usingģ. Load the pdb file 1IND using the command fetch:

Move the structure using your mouse/touchpad.Īccording to you OS, one or two windows should appear: the external GUI / command window and the viewer windowĢ.
