Hi Greg, I know this is many months later, but I'm sorry I missed your message. I thought I was subscribed to this forum, but apparently I was only subscribed to the "general discussion" subforum. I'm glad you were able to figure it out! We preserve basically every DICOM tag that we can. The only ones in tag_blocklist are there because we are overwriting them elsewhere or because they would indicate that the image was mosaic or enhanced, when that would no longer be true after this process.

Thanks,

Chris
