Hello, My name is Atanas Radkov, postdoc in Seemay Chou's lab at UCSF. I was wondering if you could help me set up Mole on Chimera. I installed it, as well as Mono, but I keep seeing the error below. Could you please let me know if there is a way to address this error? Thank you so much for your time and help! Best wishes, Atanas Traceback (most recent call last): File "/Applications/Chimera.app/Contents/Resources/share/chimera/toolbar.py", line 26, in _guard func() File "/Users/atanasdradkov/Downloads/Mole2_plugin/MOLE2_5/MainWindow.py", line 954, in <lambda> icon, lambda d=chimera.dialogs.display, n=MainWindow.name: d(n), 'MOLE 2.5', None) File "/Applications/Chimera.app/Contents/Resources/share/chimera/dialogs.py", line 76, in display dialog = find(name, create=1) File "/Applications/Chimera.app/Contents/Resources/share/chimera/dialogs.py", line 61, in find return d() File "/Users/atanasdradkov/Downloads/Mole2_plugin/MOLE2_5/MainWindow.py", line 353, in __init__ with open(CONFIGFILE, 'w') as f: IOError: [Errno 13] Permission denied: '.MOLE_PluginSettings.txt' Error in toolbar callback: IOError: [Errno 13] Permission denied: '.MOLE_PluginSettings.txt' File "/Users/atanasdradkov/Downloads/Mole2_plugin/MOLE2_5/MainWindow.py", line 353, in __init__ with open(CONFIGFILE, 'w') as f: See reply log for Python traceback.
