Proposal to an add on
by Noriega, Heather 31 Aug '22

31 Aug '22

Hello, I hope everyone is doing well. I know I have asked this before about the molmaps and have been trying to work around the "holes", in order to create a solid map for the inner volume calculation. It works very well with the AAVs, however with the other subfamilies because of their larger pores it makes it to where it is an inconsistent volume contour, and I believe it throws off the inner volume calculations. I propose to add an element to only cover the pores as a means to make the contour thinner to create a more realistic inner volume calculation. I would like to help with this feature, as my skills have improved within the last year since I first started using Chimera and ChimeraX for my project. I am unsure how I go about this and your response. I have reached out before and most of the time it ends in maybe trying another software. There is no other software that is remotely comparable to this molmap feature that is as user-friendly as it is in ChimeraX. I would really like to continue the use of ChimeraX. I have also thought of possibly trying to create a way for the molecular surface to work with the volume blob feature, but it still comes down to the pores creating the holes. A mechanism to create a feature of only covering the pores could be useful for not only my project but others that may have similar issues. Please let me know what your thoughts are as I would like to contribute to this resolution, but would also need some direction on how to start it. Thank you and I hope to hear from you soon. Thank you, Heather Noriega PhD-Pharmaceutical Science student Howard University heather.noriega(a)bison.howard.edu 520-203-1883

Displaying the main chain of residues
by Diksha Parwana 31 Aug '22

31 Aug '22

Hello, I want to display the main chain as well as the side chain of my selected residues. The main chain is only displayed when I use the hide cartoon feature. Is there some way I can see the backbone of my residues without deleting the chain as I don't want to break the continuity? I want to study both backbone and side chain interactions of my residues. Please let me know if there's a way. I'll highly appreciate it. Thanks & regards,

Help with Zone features
by Binh Nguyen 31 Aug '22

31 Aug '22

Dear ChimeraX developers, Would you please show me how to make this following figure? [cid:01baf593-38aa-4ef0-8392-146a9fb2e78d] I have learned that this is a feature in zone feature and probably solvent accessible surface, but I do not know how to make it. Any hint is much appreciated. Warm regards, B _____________________________________________ Binh A.

Color atoms by kdHydrophobicity
by Daniel Gurnon 30 Aug '22

30 Aug '22

Hi all, I use Chimera mostly for teaching purposes, and while Chimera X is definitely more user friendly for students, there are occasionally things I like from the legacy version that I can't find on a menu in the new program. One such feature is "Render by attribute". While the mlp command can create a lipophilicity surface, when I teach protein folding I like to have students visualize all atoms, with residues colored by kdHydrophobicity. Is there a simple way to implement this? Thanks Dan ____________________________ Daniel Gurnon, Ph. D. Associate Professor of Chemistry and Biochemistry DePauw University Greencastle, IN 46135

Moving/aligning/ modifying the model

Dear colleagues, Is there a way I can move(rotate) the chain/residue within a model in ChimeraX? If yes, then how? Thank you in advance. Kind regards, Dmitry

Zooming into the areas on click
by Dmitry Semchonok 29 Aug '22

29 Aug '22

Dear colleague, For presentation purposes: I would like to show the full map/model structure, then I would like to zoom in on particular areas: area 1, then area 2, then…. (preferably in motion). How is it possible to do in chimeraX? Probably as a movie? How? Thanks in advance! Kind regards, Dmitry

Can I change the curved cylinder into a straight one?
by 王超(Chao Wang) 28 Aug '22

28 Aug '22

Dear All,After displaying helix in cylinder mode, I found that it is curved by default. I would like to ask whether it can be changed to a straight shape with two ends as fulcrums or other straight way?Thanks,Chao.

Questions on job status
by Will Grubbe 26 Aug '22

26 Aug '22

Hello, I've submitted a few jobs using ChimeraX and am wondering how to check the status of them. I just need to fill in a few residues in a protein complex with known sequence - where can I find the results when they are done? Thank you for your help, Will

Imod map values
by HONG ZHAN 26 Aug '22

26 Aug '22

Dear all, It might be not a good question regarding chimeraX. I have a PEET generated averaged map and output of PEET is reversed vs. single particle maps. What is a good function to change the density of PEET output? I used newstack -multadd -1,0 function in imod, however it gave -137 level… Thanks! Hong

3d-SNFG representation of glycans
by Varga Julia 26 Aug '22

26 Aug '22

Dear All, I am trying to visualize glycans in ChimeraX, however I cannot find the possibility to use either the 3D-SNFG, nor the filled planar representation. Am I overlooking something? Is there a possibility to do this? [image: image.png] Thank you very much! Best regards, Julia Varga
