Dear All,

I have been experimenting with resolution limits in CNS in order to simulate
a low resolution scenario. I increase the high resolution till there are
thrice the reflections as number of atoms in the structure. Most of the
times this works but sometimes CNS aborts with this message:

--------------------------------------------------------------------------------
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 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 not be used
%NAYBRS error encountered: Less than two data points for
interpolation/extrapolation
--------------------------------------------------------------------------------


Surprisingly I did not get anything useful after googling for this. Does
anybody know a wokaround? Or is this to be expected if number of reflections
is low?

Thanks in advance,
Swanand
