Re: [ccp4bb] XDS problem

[Kay Diederichs]

Dear Xinghua,

it seems that you have hit a bug: assert violation indicates that an internal 
error has occurred, i.e. some situation was hit that the program is not 
prepared to handle.
There must be something very special about your dataset - maybe a very small 
number of reflections, maybe only negative intensities, maybe something else - 
which triggers the bug.
Please help me fix this - send at least XDS.INP, INTEGRATE.HKL, and all *.cbf 
files to me, by email, or put them into a Dropbox folder and send me the link.

thank you,

Kay

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).
 ab  ISa
 6.303E+00  3.806E-036.46
 !!! ERROR !!! ASSERT VIOLATION IN RESTHKL

How would this happen? How can I get through this?

Thanks in advance for your kind assistance.

Best wishes

Dr Ivan Sutherland, often dubbed Father of Computer Graphics was one 
of three laureates honored at the 28th Annual Kyoto Prize Ceremony held 
today in Japan,


The Kyoto Prize http://www.inamori-f.or.jp/e_kp_out_out.html is an 
annual international award presented in three categories to honor those 
who have contributed significantly to the scientific, cultural and 
spiritual betterment of mankind...

All of us in the crystallographic community have benefited from advances 
in visualization traceable to Sutherland. Congratulations to him.

Re: [ccp4bb] hkl2000 install

[王瑞]

ok, thanks for all of you!

 Dear everyone:

   I'm sorry for a little off-topic! I want to install HKL2000 on
 ubuntu11.10 32bits, but it produces a file named info not cr_info
 after  run the access_prod program.And when I put info to

 /usr/local/lib directory and typingHKL2000 in terminal, it display:
 root@ubuntu:/usr/local/bin# HKL2000
 ERROR: Not a valid HKL-2000 license: Licence info file (cr_info) not found
 Error code: -1

 So could anyone tell me how to do it ?
