It is a very nice webinar. Gives me the clearcut idea for
statistics and how it will be useful.

Build a reasonable model of your structure and run paired refinement afterwards using higher and higher resolution data. For that purpose, you may use program PAIREF (https://pairef.fjfi.cvut.cz/). PAIREF also works for PHENIX users and it is very easy to install.

> PHENIX contains paired refinement as well. It should be somewhere in the most advanced version of the refinement? It does the same thing, but the report from the job is focused differently. We report merging data statistics and some other parameters. Moreover, PHENIX itself does not allow complete cross-validation that we strongly recommend to the users.
