Molecular Dynamics Simulation RMSD for only spesific atoms
by Barış KURT 27 Sep '22

27 Sep '22

Hello, my intention is to plot RMSD chart for only Pd,Cl,Cl,C atoms (their numbers are 1,2,3,4). But I couldn't find a way to do it.Also II want to plot dihedral RMSD for all atoms except C,H,Cl,P atoms.How can I do that? Thank you

Hi, Does Chimera have a built-in function to save the map after it is fit into another map? The current save map could not save the new orientation and new location. Thanks, Weimin

Centering icosahedron and capsid in the same place in Chimera
by Elaine Meng 15 Sep '22

15 Sep '22

Hi Heather, Maybe your other capsid coordinates just happened to be centered on the default location for centering the icosahedron, but this one has offset coordinates. Still you could just move one or the other (capsid or icosahedron) so that they are centered in the same place. In Chimera (not ChimeraX) you can deactivate/activate models for motion so that only the active ones move with the mouse. I.e. uncheck the model number in the "Active models" list under the command line so that only the other one moves with the mouse. Other ways described here: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/mouse.html#activedef> I cc'd Chimera-users because the details in this message are about Chimera rather than ChimeraX. I hope this helps, Elaine ----- Elaine C.

Pdb saved in Chimera not displaying upon opening
by Magdalena Riad 09 Sep '22

09 Sep '22

Hi, I have opened a pdb structure of a ribosome, hidden parts of it and then saved a new pdb of the displayed atoms through “File->Save pdb” ticking “save displayed atoms only”. When I try to open this saved pdb file, Chimera states “Opened ….pdb”, however, it does not display. The model panel is empty etc. Checking the pdb file in textedit, it does contain the secondary structure information and all the amino acids but it seems to lack coordinate information, see pictures below of parts of it. I’ve also tried to save the pdb through “Actions-> write pdb”. Do you know how I can solve this issue? Is it a saving issue or a displaying issue?

How to caluculate buried surface area
by Kenji MATSUI 07 Sep '22

07 Sep '22

Dear Chimera I am sorry to interrupt your busy schedule. My name is Matsui, and I am a second-year master's student at a Japanese university. Thank you for taking time out of your busy schedule to respond to my question the other day. We are investigating the buried surface area to see the magnitude of the interaction between protein and ligand. For this purpose, I calculated the solvent accessible area of the ligand. However, the value is 9955, which shows the entire surface area of the protein. What should I do? I am not in a hurry for answers , so I would appreciate a reply when you have the time. In this case, the ligand was in the binding pocket of the protein, so I would like to calculate the ligand's solvent contact area = buried surface area. I tried to check and tried , but it did not work. 1.See https://www.cgl.ucsf.edu/pipermail/chimera-users/2009-January/003521.html 2.Try to use measure blob using chimera X.

Hi Wayne, Chimera crashes usually are caused by graphics driver bugs or running out of memory. How large is your map? By the way, we stopped developing Chimera more than 6 years ago and you would be better off using ChimeraX which is the modern version of Chimera which we actively develop.

Query Regarding processing protein in Chimera

Sir/Ma'am, I have query regarding chimera, through command line I want to select a particular residue and delete the remaining protein and save in the .mol2 file for further processing for my project.I used the following command to select the residue: select :30 for selecting the desired residue. Can you give me an insight as to how to delete the remaining protein and save in the .mol2 format. That will be very helpful.

When you open the structure, it may already be displayed as ribbon and sticks. Do not show the surface. (Or, if you already are showing the surface, you can hide it with menu: Select... Clear Selection, menu: Actions... Surface... hide) Then you can use the "rangecolor" command to color protein ribbons/sticks by hydrophobicity: rangecolor kdHydrophobicity min dodger blue 0 white max orange red See rangecolor help <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/rangecolor.html> That command is part of the tutorial for surface coloring: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html#h…> However, when the surface is not shown, you can see that this comand also colors the other representations (ribbons and sticks).

Question regarding RMSD
by ALI, MUNIRA (PGT) 16 Aug '22

16 Aug '22

Good morning, I have conducted a superposition between two of the same protein where one was obtained by X ray and the other was predicted by alphafold. I wanted to use the RMSD value of the alignment rather then just have qualitative results but I am unsure of how to interpret the values given by chimera. When I get the output of for example: RMSD between 189 pruned atom pairs is 1.164 angstroms; (across all 553 pairs: 10.750), what exactly do these two outputs mean, which one should I be using and how exactly do I interpret this? Kind regards, Munira

Trouble generating surface
by Heilman, Destin 12 Aug '22

12 Aug '22

Hi, I’m trying to generate a square surface between 4 markers to trace an atomic plane. I’ve created a marker file (attached) with the positions of the 4 atoms and when I select all markers and use the Volume Tracer tool to generate the surface, I see it show up in the Model Panel but it is not visible (see screen shot - I’m trying this in a random PDB file to test). The Volume Tracer tool also says “No surface” despite the Traced surface showing up in the Model Panel. I notice that there is no color next to the traced surface as well. It’s likely something silly I’m missing but I would appreciate help with this. Thanks.
