Dear Boaz,

yes, sure, there is the original fortran program to run it through a command 
line, and there is also a GUI (python) version. I'll send it to you off-list. 
There are a few imperfections and a minor "bug" that we noted, and we hope to 
fix them next days, but the program is "operational" and you can try it.

With best wishes,

Sacha

...
Have the criteria that you propose for determining the effective resolution 
been implemented in any program or crystallographic suite in way that we can 
read in a data set and get out the effective resolution based on your criteria?

  Cheers,

              Boaz

Dear Dale, dear Kay,

last year, we discussed this kind of problems (Urzhumtseva et al., 2013, Acta 
Cryst., D69, 1921-1934).
Our approach does not tell you where to cut your data and which reflections to 
accept / reject but as soon as you have your set of reflections, you calculate 
very formally and very strictly the "effective resolution" of ANY diffraction 
data set, with ANY completeness, with ANY composition of measured / missed 
reflections.  For a complete data set, d_effective coincides with the d_high 
value but is different for incomplete data sets. The article contains a number 
of examples.

With this approach, the discussion of the completeness of the 
highest-resolution shell becomes irrelevant; one can simply cite the "effective 
resolution". I hope this can help.

With best regards,

Sacha Urzhumtsev

   I see no problem with saying that the model was refined against every
spot on the detector that the data reduction program said was observed
(and I realize there is argument about this) but declare that the
"resolution of the model" is a number based on the traditional criteria.
