Dear editors: thank you for your excellent work. I had a problem. After i built my protein model, it was shown in software as:but when i tried to save the result, the output was displayed as so could you tell me how to solve this problem? look forward to your reply, thank you

Error from running headless Chimera
by Zhe Wang 03 Aug '18

03 Aug '18

Hi, I am trying to using headless Chimera on RedHat linux server 7.3 to produce some images. But I end up with a segmentation fault. Does anyone have an idea how it comes to this? The headless chimera is from https://www.cgl.ucsf.edu/chimera/download.html (64-bit daily build). The test code was taken without changes from https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/basicPrimer.html. Any ideas will be appreciated. Best, Zhe PS: OSMesa 11.2.2 has been installed.

A single component of the surface was calculated correctly - the failure occurred for disconnected additional components such as inside bubbles. If the desired surface is already shown, there is no need for concern. However, if it is not shown, see below for possible fixes. Surface calculation frequently fails for large, multi-chain structures. The calculation may be successful if the chains are treated individually, by using the "split" command before generating a surface. If splitting is not desired or the structure is already a single chain, changing molecular surface parameters in the Selection Inspector or (before surface creation) the New Surfaces category of Preferences may allow the calculation to succeed.

Activation buttons (namely "All")
by Eric Pettersen 01 Aug '18

01 Aug '18

Hi all, The activation buttons below the command line have an “All” button that works much the same way as the “activate all” button in the Model Panel works: if you check it on, then all models are activated for motion; if you check it off then the previous activation states are restored. It has been suggested that the behavior could instead be that when checked off all models would be deactivated (making it easier in some cases to go from moving all models to moving just one). I’m trying to find out if any users make strong use of the current behavior of that button and wouldn’t want it changed. Conversely, I wouldn’t mind hearing people who would really like to see the behavior switched. Regardless of the outcome of the discussion, the behavior of the corresponding Model Panel button would remain the same for a couple of reasons: 1) when clicked, the text of the button changes to “restore activities” so there’s less chance of confusion, and 2) there’s a separate “deactivate” button. I will interpret lack of feedback as “sure, go ahead”. :-) —Eric Eric Pettersen UCSF Computer Graphics Lab
