+The files are in compressed NIFTI (.nii.gz) format and collected in separate folders for T2 and ADC images. Each filename contains the following information (separated by underscores):
 
-"PROSTATEx Patient ID" "_" "Finding ID" "_" "Sequence name"_ADC/T2_ROI
+"PROSTATEx Patient ID" + "Finding ID" + "Sequence name"_ADC/T2_ROI
 
-As sometimes multiple axial ADC/T2 image sequences are available for a patient, the repository also includes a list in CSV format containing the correct images for each mask. The list is structured as follows:

 The sequence number corresponds to the number at the beginning of the PROSTATEx dataset DICOM image folders for each patient.
