Hello Farah,
I assume you want to add more Contour Data to the ROIContourSequence. The ROIs of the dicomContours object can be expanded dynamically by directly setting the next element of ContourData array of an item, whose original size is 813, by accessing the struct data as follows with dot indexing:
info.ROIContourSequence.Item_2.ContourSequence.Item_12.ContourData(814) = 401.13;
The length of a ContourData array of an item within the ROIContourSequence is updated dynamically when the above statement is executed.
However, if you want to add a new ROI sequence to the ROIs property of dicomContours object, please refer to the below documentation of an example illustrating the workflow to add and modify ROIs: https://www.mathworks.com/help/images/add-and-modify-rois-of-dicomrt-contour-data.html
Hope it helps!
