Hi John,

thanks for you question!

No, phenix.refine does not create the deposition ready PDB file header. 
However, there are lots of information in the PDB file header so you can 
extract it and format the way you want.

This is a question for Tom Terwilliger. I hope he will answer it.

Different programs use different dictionaries for the standard geometry, 
so it's not surprising the migrating from one program to another you get 
slightly different values.

Also, it is important to look at the values at right moment: for example 
if CNS gave you 0.0218 A but  phenix.refine says it it 0.007A, to me it 
looks like phenix.refine already did some refinement and as result the 
values are not really comparable.

Please, let me know you still have questions!
