I had been working on Dicom files and recently switched to txt files exported by inhouse functions. I was trying to use the createMask function to convert structure contours into binary masks. However, I don't use Dicom files any more. So I wrote the same information as in the dicomcontours object into a structure and fed it to the createMask function. Then I realized that createMask does not accept data types other than dicomcontours as the first input. Is there a way to convert the structure into a dicomcontours class or hack into the createMask function to force it to allow my input? Any comments are appreciated!

Not sure what kind of information is available in your structure...

@Walter Roberson Thanks for the info! The function createMask is preferred is because it requires minimum amount of changes in my previous code that works with Dicom files. I have converted my txt files into a similar form as in dicomcontours. Now what I'm doing is saving an empty dicomcontours object and add new contours into it. Not sure if this will cause problems later.
