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.

Copy protein orientation
by SANDOVAL, KENNETH 06 Sep '21

06 Sep '21

Hello, I wish to generate two images. The first is of protein A which is in session 1. The second is of protein A aligned with protein B using TM-Align which is in session 2. I wish for the alignment of the second image to be in the same orientation as the first with respect to protein A. Is there a feature which lets me do the following: 1) Identify orientation of protein A in session 1 2) Copy that orientation 3) Apply that orientation to protein A in session 2 4) Have protein B in session 2 remain aligned to protein A despite the new orientation Thank you, Kenneth Sandoval

ITasser model looks different once PDB opened in UCSF Chimera
by Athena Andreosso 26 Aug '21

26 Aug '21

Hi, I recently submitted a sequence to get a model in PDB format. When I opened the PDB file of model 1 in Chimera it looked completely different than the model on the ITasser results page - it had less beta strands. When I clicked on model 2 it was better but there's still a visible discrepancy. Am I doing something wrong? Am I supposed to give chimera more info than just the PDB file ? Any help is appreciated.

3D Visualization
by Song, David 25 Aug '21

25 Aug '21

Hi, My name is Dave Song, and I am a graduate student interested in visualizing protein structures in 3D. I was wondering if you had any recommendations in regards to computer hardware requirements for maximum performance while using Chimera/ChimeraX. Additionally, do you have any suggestions on monitors and 3D glasses that work well with Chimera? Thank you for your time, and I look forward to hearing from you. Best, Dave

Hollow Sticks When Exporting as STLs?
by Josh Moon 17 Aug '21

17 Aug '21

Hello, I hope to make this question as direct and simple as I can! When I export a scene of a molecule displayed as a ball-and-stick as a STL, I find that many of my "stick" portions are hollow. This creates thin, weak walls for 3D printing. I've included a screenshot of an intended plane cut from Meshmixer so that you can see the internal structure. What am I doing incorrectly? Is there something I can do in Chimera to export a solid object with no "hollow tubes." Fixing this with 3d programs can be time consuming.
