Why do I receive missing attribute errors when using the DICOMANON function in Image Processing Toolbox 5.0.2 (R14SP2)?

When using the DICOMANON function in Image Processing Toolbox 5.0.2 (R14SP2):

dicomanon('image.dcm','anonimage.dcm','update',values);

I receive the following error:

 Error Messages: ??? Error using ==> images\private\dicom_copy_IOD

 Missing required attribute (0008,0016) "SOPClassUID"

 Error in ==> dicomanon at 129

     dicomwrite(X, filename_out, metadata, 'createmode', 'copy');

This behavior occurs when the source DICOM image is missing the "SOPClassUID" attribute. The following code example demonstrates how to work around this issue:

imageInfo=dicominfo('image.dcm');

values.MediaStorageSOPClassUID=imageInfo.SOPClassUID;

dicomanon('image.dcm','anonimage.dcm','update',values);
