[Chimera-users] default directory for opening files

Preferences generally gets updated more frequently than that.  It gets updated whenever you click ‘Save’ in the Preferences dialog.  It gets updated whenever you use a file dialog.  So, a lot.

Though these values are used and preserved via Python, it isn’t being done in a way that is easy to control from an external script.  The easiest way, assuming you are willing to edit the source code, is to change line 381 of chimera/tkgui.py in the latest Chimera to add “initialdir=‘wherever-you-want’” to the keywords being given to the _ImportDialog constructor.

It would be a pain to do it all the time, but you could probably script something semiautomatic.  Another approach I’ve taken occasionally to ensure keeping the environment exactly the same is to have a non-writable preferences file, but of course then you can’t save any other preferences either, and there is an annoying message upon startup.

The two options are:  the directory you last used (even from the previous session) and the current working directory.  This choice is controlled by the “Open dialog starts in directory from last session” option in the General preferences category.
