Hi Young-Jin,


- computes the R-factors using all data available,
- extracts the R-factors from PDB file header (if available),
- extracts resolution limits as well as sigma cutoffs from PDB file 
header (if available) and re-computes the R-factors using these cutoffs.

This is why you get three sets of Rwork/Rfree.  Obviously, they may be 

Please let me know if it's still not clear.
