TypeError: FileSelector.__init__() got an unexpected keyword argument 'default'

Hi, thanks for developing this, I am excited to try it out.

I am unable to load the GUI, I've tried both Option 1 (jupyter notebook) and 2 (python script) from your Current Protocols paper, and as soon as I run the PhAT_gui_script.py I get a TypeError:

TypeError: FileSelector.init() got an unexpected keyword argument 'default'

Do you know what the fix for this is?
Thank you very much!

Hi Alex!

I have recently begun trying to use this protocol and I am currently receiving the same error you did. I tried editing the code to circumvent the issue, however I then received the same message for a different keyword argument ('background').

I realise you never received an answer on here but I was wondering if perhaps you have managed to solve this issue and would be willing to share the solution with me.

Thank you so much,
Barbara
