Hi Tom, Thank you for confirming it. I received two types of errors, and this explains. I can confirm that running "devel install <package>" works fine. Thanks! Best, Siyoung On Tue, Dec 23, 2025 at 5:27 AM Tom Goddard <goddard@sonic.net> wrote:

Hi Siyoung,

I also get the error you report if I try to run "devel install tut_read" twice. The first time I run the command it works with no error. So my guess is that you already have the tut_read bundle installed and don't need to install it again.

It of course should work when you try to install it again (e.g. maybe you have modified the code and want to reinstall). I've opened a ChimeraX bug report so that problem will get fixed.

Hello,

I recall installing support for the XYZ file format by following the tutorial for older versions of ChimeraX, which worked as expected:

https://www.cgl.ucsf.edu/chimerax/docs/devel/tutorials/tutorial_read_format....

However, in recent ChimeraX versions (1.10 and 1.11), the same procedure no longer works. When running devel install, I encounter the below error message. I was wondering whether the documentation might need to be updated.

Thanks. Best, Siyoung
