 XNAT organizes data by Project. Each Project has private control of its data and a user must be granted access to a Project to view or edit data. XNAT organizes data by Project. Each Project has private control of its data and a user must be granted access to a Project to view or edit data.
  
 +==== User Roles and Permissions ====
 +
 +XNAT users can have different permissions within a Project:
 +
 +**Project Owners**: If you define additional project owners, they will have all of the permissions on your project that you do. They can read, insert, modify, and delete anything (and everything) associated with your project. They can also add additional users to your project and modify the data types associated with your project.
 +
 +**Project Members**: Members have the ability to manage the data in your project. They can read, insert, and modify subjects and experiments in your project. They cannot modify the project users and data types.
 +
 +**Project Collaborators**: Collaborators have read-only access on all of the data in your project. They cannot insert or modify data owned by your project. They can download your data and use it within their projects.

-Data can end up in either Archive or Prearchive at the completion of the upload/push process from a scanner or PACS/Sectre. This depends on project-specific settings. Namely, within a project's 'Manage' tab, it's set under 'Define Prearchive Settings'. Data always 'goes through' Prearchive briefly even if its final destination is Archive.+Data can end up in either Archive or Prearchive at the completion of the upload/push process from a scanner or PACS/Sectra.

-The above 'NA' fields are not anonymized because they are used by users to identify data within XNAT before it can be given whatever kind of unique, anonymized identifiers that a research group's study protocol specifies. Before data is pushed from PACS/Sectre and clinical scanners, the DICOM header info cannot be modified, so this information must be preserved upon entry into XNAT.+The above 'NA' fields are not anonymized because they are used by users to identify data within XNAT before it can be given whatever kind of unique, anonymized identifiers that a research group's study protocol specifies.

-When pushing data from the research scanner (which allows the user to modify the DICOM 'Patient Comments' or 'Study Comments' field before pushing the data), the user has the option to assign metadata that XNAT will use to new assign values to the some of the NA fields during import. Otherwise, the NA fields be preserved as in a push from PACS/Sectre.
