[phenixbb] phenix.xtriage says that entire res range contains anomalous signal but chart says differently?

[Francis E Reyes]

Hi all


I ran xtriage on my dataset to 4.5.here's the relevant section  
pertaining to anomalous signal

Analyses of anomalous differences

   Table of measurability as a function of resolution

   The measurability is defined as the fraction of
   Bijvoet related intensity differences for which
   |delta_I|/sigma_delta_I > 3.0
   min[I(+)/sigma_I(+), I(-)/sigma_I(-)] > 3.0
   holds.
   The measurability provides an intuitive feeling
   of the quality of the data, as it is related to the
   number of reliable Bijvoet differences.
   When the data are processed properly and the standard
   deviations have been estimated accurately, values larger
   than 0.05 are encouraging.
   Note that this analyses relies on the correctness of the estimated
   standard deviations of the intensities.


unused:         - 90.6596 [   0/1   ]
bin  1: 90.6596 -  9.2614 [1371/1382]  0.0375
bin  2:  9.2614 -  7.3520 [1369/1376]  0.0033
bin  3:  7.3520 -  6.4230 [1380/1388]  0.0000
bin  4:  6.4230 -  5.8358 [1353/1359]  0.0016
bin  5:  5.8358 -  5.4176 [1367/1371]  0.0000
bin  6:  5.4176 -  5.0982 [1361/1369]  0.0000
bin  7:  5.0982 -  4.8429 [1378/1382]  0.0000
bin  8:  4.8429 -  4.6321 [1351/1359]  0.0000
bin  9:  4.6321 -  4.4538 [1383/1389]  0.0000
bin 10:  4.4538 -  4.3001 [1390/1393]  0.0000
unused:  4.3001 -         [   0/0   ]

  The full resolution range seems to contain a useful
  ammount of anomalous signal. Depending on your
  specific substructure, you could use all the data available
  for the location of the heavy atoms, or cut the resolution
  to speed up the search.


If values larger than 0.05 are encouraging why is it telling me that  
the entire resolution contains a useful amount of anomalous signal?  
Did I process this incorrectly?


Thanks
