Question about save images
by Chang, Jufang 29 Apr '24

29 Apr '24

Hi, there, I used Chimera for a very short period of time. When I just started using Chimera I was able to save image by going to "file" and "save image" to save the image on the display window. For some reason, this stopped working. Now, after I did the same thing, the image I saved has complete blackness (attached). I wonder whether I might get be able to get help from you. I also tried using command line to save image. The result is the same. The exact procedure I used are: Go to "Presets", choose "publication 1" , then go to "File" and "save image" I used window system.

Save cut open model for 3Dprinting
by Haselbach,David 03 Jan '23

03 Jan '23

Hi, I wanted to build a cut open model of a cryoEM map which I achieved through clipping in Chimera. But I am failing to apply the clipping in a way that I can save the cut open mesh as poligone file for 3D printing. Is this possible? All the best, David

Is there an option to open pdbqt as PDB format smoothly?
by 夏前程 27 Dec '22

27 Dec '22

Hi Chimera team, I'm wondering if there is any chance that I can open a .pdbqt file smoothly (just like open a .pdb file ) through some strategies (for example, maybe modifying some source codes?). Since AutoDock (and vina) always gives a .pdbqt format file but not .pdb format, however the content of which is somewhat like pdb and we always want to open it in pdb format. This is not an important issue. But if so, the experience will be much better at least for me (Now, I have to choose the PDB format or rename the file suffix into .pdb). With Regards Qiancheng Xia 2022/12/23

Chimera startup error: "Display misconfiguration" (Debian GNU/Linux)
by Powell, William A. 25 Dec '22

25 Dec '22

Hi, Chimera community. I have seen similar problems addressed, and the solution is always to update drivers and make sure there is only on OpenGL renderer. I am unable to resolve my problem this way. When Chimera is launched using my dedicated NVIDIA 3060 Mobile graphics card, there are mixed results. If launched from a terminal instance an by the NVIDIA card, it produces the error below. Display misconfiguration. Please increase the color quality (24 bit color or greater), update your display (graphics) driver, and/or upgrade your graphics card. Also see chimera installation instructions. Using primusrun, it succesfully launches on the dedicated card. Unfortunately, the nvidia-primus and bumblebee-nvidia packages seem to conflict with the NVIDIA drivers. The only way Chimera works reliably is by launching it through an instance of Steam ran on the NVIDIA card. The Steam client opens ~/.local/bin/chimera, the same file opened through the terminal. I am not sure what is so special about launching an application through Steam. Thanks! W.

Hi Sette and again Chimera team,I know what you said. But what I really want to ask is that if there is any way to open .pdbqt smoothly just like .pdb (without the format-choosing step). Just imagine the suituation of mine: I have to open like 10 .pdbqt file in a chimera session. If I didn't rename the suffix from .pdbqt to .pdb, I have to choose format for 10 times. That should be a bit annoying for me. So I ask the question here to find some smart solutions...With regardsQiancheng Xia2022/12/24> Hi Qiancheng, > > as far I know the File-Open allows to open a .pdbqt file. > simply > choose pdb in the list of possible formats. > > Best > > Marco > > Il 23/12/2022 14:20, ??? via Chimera-users ha scritto: > > > > Hi Chimera team, > > > > I'm wondering if there is any chance that I can open a .> pdbqt file > > smoothly (just like open a .pdb file ) through some > strategies (for > > example, maybe modifying some source codes?). > > > > Since AutoDock (and vina) always gives a .pdbqt format file > but not > > .pdb format, however the content of which?is somewhat like > pdb and > > we always want?to open it in pdb format. > > > > This is not an?important issue.

Hi Qiancheng, as far I know the File-Open allows to open a .pdbqt file. simply choose pdb in the list of possible formats.

Question about Labeling Beta Sheet
by Yifan Wang 22 Dec '22

22 Dec '22

Hi Chimera team, I have a question for labeling beta sheet. After I get secondary structure, when I look at the 3D structure, It is very clear to see coli, helix and beta-strands. But how can I label and tell the beta strands are in same sheet or not? Does chimera contain the information for beta sheet? Thank you so much! Yifan

AttributeError of "Model Panel" when using nogui mode to save session

Chimera
by Добромир Калчевски 19 Dec '22

Hello, I would like to suggest an improvement in the GUI: when a data set of multiple files is opened (for example multiple .cube files) the Volume Viewer displays options (including hide / show) for only 3 of them. There is no scroll up or down. Resizing the window does not change the number of loaded files to manipulate for visualization. Let's say I want to browse a set of 12 molecular orbitals - I have to manually click on each one in the "Data set list", then click the hide (eye) icon in the detailed options list below and do this for all molecular orbitals / .cube files, otherwise Chimera visualized all of them at the same time. It is simply not convinient to hide and show them if I want to view more than 3 files in the Volume Viewer. In ChimeraX that issue does not exist, yet it lacks working linux binaries (too many dependencies to cover outside of distros like debian ot red hat, especially if the dependencies are not explicitly mentioned and the distro does not provide them with a package manager). Best Regards, Dobromir

Dear all, When I fetch a protein with a chromophore (PDB code 2h5q), the chromophore, not a standard one, is missing, and not present in the Select-Residue menu. Is there any way to obtain it?
