The size of the segmentation image (DICOM-SEG) does not match the size of the main image (DICOM)

Operating system: win 10
Slicer version: Slicer 4.11

Hi Everyone,

As shown in the figure, I downloaded the LIDC-IDRC dataset and standardized representation of the TCIA LIDC-IDRI annotations using from TICA , and then use the dcmqi to convert DICOM-SEG format files to nrrd format files.
They can be opened and feature extraction well in 3D-Slicer, but I want to use the python library radiomics with programming to do feature extraction, and the dimension does not match when reading the data. Similarly, when reading those data with ITK-snap the same problem also appeared at the time, is there any way to solve it? Or, is there any way to change the dimension of the 5125128 annotation file to be the same as the 512512133 of the source image?




Thank you all !!!
