Use function dicomContours

The Modality Attribute showing 'NM' and hence the attached files are NM dicom images only.

So you are not able to open any RT structures since it is not a RT structure file.

HOW ABOUT THIS ATTCHED FILE SIR? IS IT CORRECT FILE RT STRUCT?

[Simon Chan]

Your attached zip file has 5 folders, and you may guess what type of data was inside each folder from its folder name. Provided the naming is correct, the folder name contains the word "....._RTst_....." has the DICOM RT structre file inside.

Then, you can use function dicominfo, dicomContours and plotContor to retrieve the RT structure information from the DICOM file. The following one shows the result from one of the DICOM RT Structure file.

On the other hand, you may also use function dicomlookup to check the Modalty Attribute in order to make sure the file is a DICOM RT Structure file.

filename = unzip('2.16.840.1.114362.1.11854208.23879450333.559219930.834.zip');
info = dicominfo(filename{1});
info.(dicomlookup('0008', '0060'))      % Check the Modality Attribute

ans = 'RTSTRUCT'

contour = dicomContours(info);
plotContour(contour)
