I am trying to make a loop over several folders using a path for my function but when I test the code I get
subject_number = "45";
maindir = sprintf('/Users/Baso/Desktop/TMM/TMM%s/m2m_TMM%s', subject_number,subject_number);
part = sprintf('/TMM%s_tms_PH_simu', subject_number);
S.subpath = maindir;
S.subpath = fullfile(maindir, part);
I keep getting the error "TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType"

That is a Python error: it refers to Python's inbuilt "os" module:
and to Python's object type "NoneType":
You should be asking on a Python forum.

Hi Reuben,
I understand that you are facing an issue while trying to loop over several folders using a path. The error message "Typeerror: stat: path should be string, bytes, os.pathlike or integer, not NoneType" occurs when you are trying to perform a file operation and the path that you have provided is not a valid path.
To resolve this error, you should check that the path you are providing is a valid file path. You can use the "exist" function to check if a file or folder exists. Kindly refer to the following link to go through the "exist" function.
You should also make sure that the path is formatted correctly and that you are using the correct file extension.
I hope this answer resolves the issue you are encountering.
