Hey, Just want to add that QRegularExpression is in Qt5, so you should be able to use that and have it work with ChimeraX 1.3 and the daily builds. QRegExp was a different thing and apparently, they phased it out in Qt6. Hopefully, you don't need to make too many changes, as QRegExp and QRegularExpression are somewhat different.

I tried your suggestion and it works partially but there are some issues. For instance I am getting: cannot import name 'QRegExp' from 'Qt.QtCore' And I am also not sure how to set this up with pycharm as there is no module actually named just Qt. Which means I am getting red squiggles all over and it breaks the autocomplete. I am also curious as to why adding PyQt5 to the dependencies doesn't work. fre. 8. apr. 2022 kl. 17:26 skrev Anthony James Schaefer <tony.schaefer@uga.edu<mailto:tony.schaefer@uga.edu>>: Is the other computer running a ChimeraX daily build? They are looking to switch to PyQt6 in one of the next versions. A ChimeraX developer would have more details on that. Try changing your PyQt5 imports to just "Qt" (e.g. from Qt.QtWidgets import QPushButton). ChimeraX uses a shim to make things less dependent on the version of the Python Qt wrapper.
