Dear All,
I am working on a low resolution data (4A) and when I run annealing in
CNS, I get the following error:
*************************************************************************************
 NEXTCD: condition evaluated as false
 Program version= 1.1 File version= 1.1
 Sum of       187 elements =               187.0000
 Sum of       187 elements =               187.0000
Warning: there are less than 50 reflections per bin
         you may want to increase the size of the test set
 Sum of      2004 elements =              2004.0000
 Sum of         0 elements =                 0.0000
 Problems interpolating or extrapolating data.
 Input data had the following distribution:
Data point     1 could not be used
Data point     2 could not be used
Data point     3 could not be used
Data point     4 could not be used
Data point     5 could not be used
Data point     6 could be used
Data point     7 could not be used
Data point     8 could be used
 %NAYBRS error encountered: Less than two data points for
interpolation/extrapolation
   (CNS is in mode: SET ABORT=NORMal END)
 *****************************************************
 ABORT mode will terminate program execution.

Could someone help me out?
Thaks & Regards
