Katie, I'm not sure. I tried adding pdb-objects to one of my bundle's dependencies, and it was installed. I'm testing this on a ChimeraX 1.4 daily build. My bundle_info.xml has this: <Dependencies> <Dependency name="ChimeraX-Core" version=">=1.2.dev"/> <Dependency name="pdb-objects"/> </Dependencies> and my log has this after installing (along with a bunch of other stuff): Looking in indexes: https://pypi.org/simple, https://cxtoolshed.rbvi.ucsf.edu/pypi/ Processing c:\users\normn\documents\github\chimerax_themes\dist\chimerax_themes-0.3.1-py3-none-any.whl Requirement already satisfied: ChimeraX-Core>=1.2.dev in e:\chimerax 1.4.dev202202010639\bin\lib\site-packages (from ChimeraX-themes==0.3.1) (1.4.dev202202010639) Collecting pdb-objects Using cached pdb_objects-0.1.3-py3-none-any.whl (6.6 kB) Installing collected packages: pdb-objects, ChimeraX-themes Successfully installed ChimeraX-themes-0.3.1 pdb-objects-0.1.3 --- Successfully installed ChimeraX-themes-0.3.1 pdb-objects-0.1.3 Installed ChimeraX-themes (0.3.1) Towards the bottom, it says it installed pdb-objects and my bundle. I can then go into the shell and import pdb_objects without error.

I've now changed the dependency to pdb-objects, but I still get the same error when I try to use the bundle in ChimeraX. Have you got any idea why it's giving this error?

Katie, It looks like PDB objects on PyPI is called pdb-objects, not pdb_objects. For dependencies, ChimeraX looks for the package name and not the import name.

Following the tutorial on the website, I'm adding the following line to my bundle_info.xml file under the dependencies tag: <Dependency name="pdb_objects"/> It still gives me an error of <No module named 'pdb_objects'> when I load my bundle in ChimeraX. How can I allow the use of this library in my bundle? Thanks for your help! Best Regards, Katie
