 While CHESS provides state-of-the-art hardware, software, computing resources and trainings, **users are responsible for the integrity of their experiment** through thoughtful planning, experimental execution, and **data handling and analysis**. This includes maintaining best practices in experimental logs, metadata tracking, and recording of researcher decisions. Due to the nature of synchrotron experiments, the data integrity and intepretabilty - even within one research group - will be dependent on the practices adpoted by the research group.

 It is always the responsibility of the experimenter to take **detailed** beamtime notes and a log of the data. Although work is ongoing to integrate metadata and capture requisite information in the data itself, automate workflows, visualizations, etc., it is imperative that experimenter notes are taken and ideally a copy is kept with the data on the CHESS system.

 If you wish to move any data from the CHESS filesystem to another location, the preferred way of doing so is through Globus. Please see here (https://wiki.classe.cornell.edu/Computing/GlobusDataTransfer) for directions on ways to transfer data from the CHESS filesystem.
