[ccp4bb] 2Theta data set solving problem

2013-04-09 Thread navin narayanan
Hello everybody,

We have a diffraction data set from home source with 2theta at 20deg. But
we are not able to solve the data set using CCP4 suite. The software is
picking up only the lower resolution data but not the higher resolution
data points. Also we are not able to merge data two sets, one with 2theta
at 0deg and the other with 2theta at 20deg. Is there anyway to solve the
data. Any help will be truly appreciated. Thank you in advance.

hello everybody,
  Thank you for all your suggestions. I am able to
process the 2 data sets separately. But the problem is that I dont have an
idea as to how can i merge the 2 data sets with different 2theta values.

 Dear Navin,

 As others have pointed out, it is not clear where your problem exactly
 lies: Are you not able to process the 2theta=20° run, or are you not able
 to merge it with the 2theta=0° run? Anyways, I and others have had similar
 problems with merging high and low resolution runs, see a very recent
 thread below:

 http://www.mail-archive.com/ccp4bb@jiscmail.ac.uk/msg30764.html

 In my case, Scala would fail with low redundancy data or when there are
 too few reflections in common between both runs. What worked for me is to
 process with XDS and scale with XSCALE. For this you can use the autoProc
 procedure of global phasing, or teh Xia2 pipeline which seems to be part of
 CCP4. Using one of these pipelines will probably also solve your problem if
 you are not able to process the swing-out run.

 Good luck!
 Herman
