Subject: [chimerax-users] independent centers of rotation
Content-Type: text/plain; charset=us-ascii
Hi Abigail,
Ah, you're referring to the "independent centers of rotation" mode in Chimera. By default, the "tile" command in Chimera automatically turns it on.
I agree that this mode is very useful, but unfortunately it does not yet exist in ChimeraX. It is listed in the missing features section of the ChimeraX download page.
Sorry about that,
Elaine

> Hi there,
> I have a question regarding the tile function in ChimeraX. In the original Chimera, once multiple maps were tiled they would all rotate individually and the grid itself was fixed in space. In ChimeraX, however, once maps are tiled the entire grid rotates as a unit and the individual maps are fixed. Do you know if there is an option to have the maps spin individually instead, like in the original Chimera?

Subject: [chimerax-users] Change the directory for data fetched from
databases
Content-Type: text/plain; charset="utf-8"
Hello,
The documentation for the open command says "Web-fetched data are stored locally in ~/Downloads/ChimeraX/ (where ~ indicates a user's home directory)". Is there a way to change this directory? I couldn?t find one in the settings window, but maybe a command could do that? (in that case I would simply need to add this command to the startup commands).
The use case I have in mind is to share the ChimeraX cache between all accounts on a multi-user workstation (so, relocate the cache at some place like /data/ChimeraX).
Thank you,
Guillaume

Hi Guillaume,
There is no setting to change the location where ChimeraX caches fetched files. It is always
~/Downloads/ChimeraX
On a multi-user workstation is the idea that every person would change the ChimeraX setting to point to a common cache directory? Will people cooperate with that? Each person of course has their own ChimeraX settings. Everyone will also need write access to that directory. There are no site-wide settings in ChimeraX.
You could modify the ChimeraX application file, a file in the distribution (here's the path for Linux)
chimerax/lib/python3.9/site-packages/chimerax/core/fetch.py
making
_cache_dirs = ['/usr/local/chimerax_fetch']
near the top would I think change to use that directory. Of course each time you install a new ChimeraX it would need such a change, and if individual users install their own ChimeraX version it will use ~/Downloads/ChimeraX.

Hi Tom,
This is the use case I had in mind indeed. Model files are small enough that duplication doesn?t matter, but a shared cache for maps could be convenient. I was simply asking in case there was a supported way to achieve this that I had missed in the documentation, but I can absolutely live with the current default.
Thank you for your answer.
Cheers,
Guillaume

An alternative approach which doesn't involve modifying ChimeraX (but still requires action in each user account) would be to simply symlink ~/Downloads/ChimeraX to the centralised location.

Very simple indeed, I should have thought of that first. Thank you Tristan. :-)

Subject: [chimerax-users] PDB: 7OVR
Content-Type: text/plain; charset="utf-8"
To whom it may concern,
The command ?show sel atoms? does not work in the 7OVR structure and I was wondering how can I fix this? I wanted to show certain residues as atoms in the structure. When I open other structures, e.g. 5FMM, the command works perfectly fine.
Would you know what could be the cause?
Thanks,
Hana

Hello Hana,
I can't tell what you have selected, so it is impossible to say. Remember, the "sel" in the command means the current selection. Do you have any atoms selected?
Also, when I open structure 7ovr in ChimeraX, all of the atoms are shown already.
I hope this helps,
Elaine
