Hi All,

      Thanks for Phenix! Anyway quick question, I tried out the "generate
Table1" utility for fun and noticed that my I/SigI and completeness do not
match what is found in my XSCALE file.

   From Table 1

         Completeness (%)                   98.62 (90.57)
          Mean I/sigma(I)                     7.39 (1.59)
          Wilson B-factor                           59.78
                    R-sym
                 R-factor                 0.2006 (0.3275)
                   R-free                 0.2241 (0.3739)

How does Phenix compute these parameters? Obviously my I/sigI has gotten
much better (1.59 versus 0.85) but the scaling statistics should be the
correct ones.


                       Thanks,

                                      Drew
