Dear ccp4 users,
I have a data set arising from a nearly-perfect pseudo-merohedrally
twinned cystal, diffracting up to 3 A. I solved the structure and ready
for deposition, but there is still a trouble.
The Wilson scaling from raw data gave a B of 3A^2.
Initially, I did not seemed too alarming. But I do not know why I have
these statistics.
Does anyone know why Wilson scaling falls when treating that kind of
twinned data? I read that twinned data do not obey twe Wilson statistics
but I don't know why.
Here the presentation I read:

Do you know any articles, reviews or book in which this particular
aspect of of twinned data is treated in depth, possibly in mathematical
manner?
Thanks to all
