Description

The following bug report has been submitted:
Platform:        macOS-26.3.1-arm64-arm-64bit
ChimeraX Version: 1.12.dev202603070142 (2026-03-07 01:42:04 UTC)
Description
I am trying to minimize a structure produced by AF3 but i have type error related to a string , which i guess is a bad type casting or failed transformation in another object.  I have attached the structure for reproducibility
