[Insight-users] EncapsulateMetaData problem

[Antoine Leimgruber]

Dear all,

I am trying to edit 3 dicoms tags (see section of code at the end of the message).

When I run the code once, the output dicom image has 2 of the 3 tags edited. The tag 0028|0030 remains unchanged.

If I run the code again with the previous output image as input, then the third tag of the new output is also edited.

What can I do to avoid running twice my code on each image ?

An alternative would be to remove the tag 0018|1164 from the header. How can I do it ?

Thank you for your help

Antoine
