Dear all,

Recently i'm using both MRIcron do the tumor segmentation.

For each patient we have 2 scans: coronal and sagittal.

I found that when i draw the tumor with MRIcron on the coronal scan, the segmentation(ROI) can be used on sagittal scan (only in MRIcron, the ROI from coronal scan cover the tumor area that shown in sagittal scan)
'''
In MRICron,
when load coronalImage as main image, load coronalROI as overlap image, the ROI cover the tumor area.
when load sagittalImage as main image, load coronalROI as overlap image, the ROI still cover the tumor area well.
'''

But when i try to extract tumor feature with ITK or other tools,
featureExtraction(coronalImage,coronalROI); it work ;
featureExtraction(sagittalImage,coronalROI); error shown up.
error message said that the ROI matrix shape is different from the Image matrix shape.

I'm wondering how MRIcorn do the overlapping process, especially between 2 images with different shape.

Thank you for your help, best regards.

Ps. I attached the a patient's coronalImage, coronalROI, and sagittalImage in the attachment.
