[Chimera-users] IOError for non-existing ViewDock_Accelerator.py when executing Chimera

[Elaine Meng]

Hi Qiancheng Xia,
I don't know what that file is specifically, but my guess is that this pathname is defined in the Keyboard Shortcuts tool as the file to find definitions of keyboard shortcuts.

Anyway, if my guess is correct, you would need to start Keyboard Shortcuts (in menu under Tools... General Controls).  Near the bottom there is a button to "Load shortcuts file" and below that an entry field with the pathname of the shortcuts file.

The standard file is [where-you-installed-Chimera]/Chimera.app/Contents/Resources/share/Accelerators/standard_accelerators.py

For example, in my case that field contains:
/Users/meng/Desktop/Chimera.app/Contents/Resources/share/Accelerators/standard_accelerators.py

Maybe yours gives ViewDock_Accelerator.py instead?  I don't know what that file is (as far as I know, it's not from us), but maybe it is something you used to have but it got deleted.  If so, you could delete the contents of the field and then quit/restart to see if you still get the message.  

Another way to change that same setting is by editing your preferences file directly, but that may be difficult to do without messing up your preferences, or deleting your preferences file, but that will lose all of your other preferences.  You can see where your preferences file is by starting Chimera and looking in the Preferences (menu: Favorites... Preferences), category: Preferences.

I hope this helps,
Elaine
