How do i save all pdb files into a single mol2 file individually..what is the correct format of that mol2 file to proceed for docking in dock6?

rna-protein complex
by soo khim 29 Mar '19

Hi chimera, I have a RNA-protein complex pdb file. After modeled the missing loops in the protein and saved the pdb file for remodel protein structure, the RNA is missing in the new pdb file. How should i save the remodel protein model together with its RNA? Thank you Best Regards, Chan Soo Khim

Aligning (superimposing) chains form the same PDB files
by Jenaro Soto 28 Mar '19

28 Mar '19

Hi, Can Chimera superimpose all chains from one PDB file. If so how can this be accomplished? I have tried using the MatchMaker tool but it ask me to select at least one different reference model. I have also tried Match -> Align but it also asked me to only choose one chain per model. Any help would be appreciated.

electron density map superimposed on protein model
by Jenaro Soto 27 Mar '19

27 Mar '19

Hi Everyone, I am new to Chimera and am still getting to know the program. So far I have found the tutorials helpful, but they don't seem to have the answer to this very specific question. I want to know how I can overlay a protein structure and electron density map correctly. I am currently analyzing a published structure and would like to look at the the electron density map superimposed on the protein model. I was able to fetch the electron density map by using the 'open edsID:PDB_ID' command. However, it doesn't seem like my structure and the electron density are overlaid correctly. This might be because I moved the structure a lot before calling in the electron density map. How can I have the electron density map overlaid to the structure correctly (like the author intended it to be). Any tips will be appreciated. Best, Jenaro

drawing stereographic projections for point groups in Chimera
by Arvind SHARMA 27 Mar '19

27 Mar '19

Hi, Is there a way to draw stereographic projections in chimera or chimeraX for the point groups? I want to draw these projections for icosahedral point groups (of T=3 virus), keeping the outer shell from chimera Multi-scale Models. Idea is to make something as in attached file. Would be great if someone has ideas how to do it or a script is available. Thanks a lot. Best, Arvind.

Save multiscale model as PDB?
by Divjak Maja 26 Mar '19

26 Mar '19

Hi Elaine, Hope you're well! I'm working with measles PDB 4uft and have managed to make a multi scale model from this in Chimera. What I would like to do is save this multiscale model as a PDB and import to Maya, however, when I do this, all I get is a single subunit and not the multiscale model. I've tried looking in the Help documentation, but can't find how to save the whole multi scale model in PDB format. Thanks so much and best wishes, Maja Dr Maja Divjak BAppSc(Hons), PhD, Grad Cert 3D Animation (AFTRS) Biomedical Animator Office of Cancer Research [Description: cid:image001.jpg@01D35ECE.31407C60] Phone +61 3 8559 5961 Email maja.divjak(a)petermac.org<mailto:maja.divjak@petermac.org> 305 Grattan Street Melbourne Victoria 3000 www.petermac.org<http://www.petermac.org/> Disclaimer: This email (including any attachments or links) may contain confidential and/or legally privileged information and is intended only to be read or used by the addressee.

Change map gridding for better display
by Ahmad Khalifa 25 Mar '19

25 Mar '19

How can I change the gridding of my cryo-EM map to make it look better? I know I can resample a map in chimera on the grid of another, but I'm not sure which absolute gridding is better to view the map and how to change the gridding without a reference.

creating a new color palette - viridis
by Saladi, Shyam M. 22 Mar '19

22 Mar '19

Hello -- I see that a number of color palettes were added to chimera a little more than a year ago now: http://plato.cgl.ucsf.edu/pipermail/chimera-users/2017-September/013872.html I would like to try using viridis (https://bids.github.io/colormap/) instead of standard rainbow/spectrum for coloring a protein from its N to C termini. Would someone be able to give me direction on how to create a new a color palette to do this? The RGB values making up viridis can directly be found here: here: https://github.com/BIDS/colormap/blob/master/colormaps.py Thanks, Shyam
