Dear CCP4ers,
Recently I am trying to process a dataset with XDS program, but during the
intergrate and scale procedure it always ended with the following warning:
!!! ERROR !!! ASSERT VIOLATION IN "RESTHKL"
******************************************************************************
CORRECTION PARAMETERS FOR THE STANDARD ERROR OF REFLECTION INTENSITIES
******************************************************************************
The variance v0(I) of the intensity I obtained from counting statistics is
replaced by v(I)=a*(v0(I)+b*I^2). The model parameters a, b are chosen to
minimize the discrepancies between v(I) and the variance estimated from
sample statistics of symmetry related reflections. This model implicates
an asymptotic limit ISa=1/SQRT(a*b) for the highest I/Sigma(I) that the
experimental setup can produce (Diederichs (2010) Acta Cryst D66, 733-740).
a b ISa
6.303E+00 3.806E-03 6.46
!!! ERROR !!! ASSERT VIOLATION IN "RESTHKL"
How would this happen? How can I get through this?
Thanks in advance for your kind assistance.
Best wishes
