From an email from gleb:

best does not  read stdin  anymore, all  input on the command line.

New options are:

 -i2s  <I/SigI>, aimed I/SigI at highest resolution, default 2.0
 -T(otal) <number>, maximum total exposure(dose), sec, (default long)
 -S(peed) <number>, maximum rotation speed, deg/sec, (default fast)
 -M(inexposure) <number>, minimum exposure per frame, sec, (default short)
 -e <none|min|full>, anisotropy correction level, default <full> (-e none is
like formerly -e 1 or stdin "split  1")
 -R(redundancy) <number>, aimed redundancy, default minimum
 -C(ompliteness) <number>, aimed completeness, default 0.99
 -a anomalous on (default off)

and some more...

The normal use would be like:

a) determine resolution and strategy for this resolution for total exposure
time 100 sec, max.rotation speed 5 deg/sec, min exposure time/frame 0.2 sec
and <I/SigI>=3 in the last shell  :

best -T 100 -S 5 -M 0.2 -i2s 3 -f ccd -t 1 -dna best.stf -e none -mos
bestfile.dat  bestfile.par bestfile0.hkl ...

Note that default i2s is 2 , not 3 as before !

Most of the output did not change, the following is added:

   <table name="general_inform" index="1">                                                         
        .........
       <list name="ranking_resolution" index="1">                                                    
          <item name="isigi">3.00</item>                                                              
          <item name="dmin">1.45</item>                                                               
          <item name="sigma_dmin">0.06</item>                                                         
      </list>                                                                                       
 </table> 

dmin is (extrapolated) resolution limit for total exposure given by -T . It
may be smaller then the resolution in the corner of the detector, but is
never bellow 0.9A, that is currently an absolute limit for all calculations
in best. "sigma_dmin" is an estimated error of dmin.
 
Another new output line is in:

<table name="data_collection_strategy" index="1">                                               
     <list name="summary" index="1">                                                               
        ..........
        <item name="attenuation">1.0000</item>                                                      
        ..........
     </list>                                                                                       

Is an attenuation coefficient,  <=1 .

b) if user-defined resolution limit:

best -r 1.7 -T 100 -S 5 -M 0.2 -i2s 3 -f ccd -t 1 -dna best.stf -e none -mos
bestfile.dat  bestfile.par bestfile0.hkl ...

in this case, if 1.7 A may not be measured within 100 sec, the strategy is
calculated for the resolution limit that can be reached (2.72 in the
example), and a following item is added to the "data_collection_strategy":

<table name="data_collection_strategy" index="1">                                               
     <list name="overdose" index="1">                                                              
       <item name="status">yes</item>                                                              
       <item name="limit">2.72</item>                                                              
     </list>                                                                                       
</table>

c) To calculate the statistics only, for fixed resolution 1.5, 90 degree
rotation starting with phi=10, oscillation 0.5 and exposure 1:

best -r 1.7 -phi 10 90 -c 0.5 1  -f ccd -t 1 -dna best.stf -e none -mos
bestfile.dat  bestfile.par bestfile0.hkl ...

c) to determine resolution/exposure time for user-defined rotation range

best -phi 10 90 -T 100 -S 5 -M 0.2  -f ccd -t 1 -dna best.stf -e none -mos
bestfile.dat  bestfile.par bestfile0.hkl ...

d) to do full strategy for user-defined redundancy (8):

best -R 8 -T 100 -S 5 -M 0.2  -f ccd -t 1 -dna best.stf -e none -mos
bestfile.dat  bestfile.par bestfile0.hkl ...

c) for anomalous data:

best -a -R 8 -T 100 -S 5 -M 0.2  -f ccd -t 1 -dna best.stf -e none -mos
bestfile.dat  bestfile.par bestfile0.hkl ...
