 This is closely related to the above discussion of equilibration.
 Depending on the relaxation timescales involved, one may realize only after analysis of a ``production'' trajectory that the system was still equilibrating in some sense.

+A separate Best Practices document addresses the critical issues of convergence and error analysis; we refer the reader there for more details (\url{https://github.com/dmzuckerman/Sampling-Uncertainty}).
 For more specific details on procedures and parameters used in production simulations, see the appropriate best practices document for the system of interest.
 
 One other key consideration in production is what data to store, and how often.
