Hello,

I'm trying to do the first level analysis using spm12.

I need to fill the 'onset' under 'condition', yet I don't have a file with the list of data in it. It seems everyone uses some kind of the already organized data files, but I only have dicom files.

How can I extract the raw data of onset time from dicom file or from anything?

Hi Lynn,

The dicomcontours object extracts and stores region of interest (ROI) data from the metadata in DICOM-RT structure set files. You can use the object functions to add, delete, display, modify, and create masks from this ROI data. You can learn more about this function in this documentation provided by MathWorks: https://www.mathworks.com/help/images/ref/dicomcontours.html

Hope this helps!
