Hello，I found that ModalitiesInStudy can’t be added to the ExtraMainDicomTags configuration, the other fields are working!
Hi,
Indeed and you even get an error message that explains why:
ModalitiesInStudy cannot be added in the Extra Main Dicom Tags since the value of this tag is computed when requested
All other tag values never changes. This tag value would change if you add/remove a series to the study.
Best regards,
Alain.
Thank you for your reply.
The ModalitiesInStudy tag is computed and updated by Orthanc only when we add/remove a series to the study or also at the time the study is first received by Orthanc? I ask because in most of the studies I have in Orthanc the ModalitiesInStudy tag is blank.
The tag is only computed when requested in a C-Find or tools/find.
