Respected Madam, In my System images path: D:/LIDC Dataset/LIDC-IDRI/LIDC-IDRI-0001/01-01-2000-30178/3000566.000000-03192/ based on this above code is not appending any data to patients and it is showing IndexError: list index out of range.

So, please provide the solution of my code , your support is going to help a lot for my research work.

hi, this problem may be caused by different folder organization. In older downloads, the data DICOM data would download as:[...]/LIDC-IDRI/LIDC-IDRI-dddd/uid1/uid2/dicom_file.dcm. However, in more recent downloads, the data is downloaded like: [...]/LIDC-IDRI/LIDC-IDRI-dddd/???. Your can go to pylidc for more detail. good luck!

Is there a way to fix this apart from trying to download the old dataset?
