Hi Sharif,
Please do keep in mind that anonymization in XNAT is a complex topic, and so hacks around it may have unintended consequences. In particular, you should double check the XML for one of your sessions (look in the Actions box on the session report page) and make sure that the original pre-anon values haven't been persisted in a way you wouldn't want.
1. You preserve the "RoutedStudyDicomProjectIdentifier" section which is how DQR uses the project you selected earlier in the process as the destination rather than attempting to derive the project ID from the DICOM headers.
2. The name of your DICOM object identifier should start with "dqr" so that the front-end recognizes it as valid for the DQR workflow.
Hopefully that helps.
Thanks,
Charlie Moore
