Hello everybody,
I am working with a protein that should be covalently bound to an
organic ligand and I would calculate the correlation coefficient of this
ligand both against 2Fo-Fc and Fo-Fc map arising from refining (map
calculated in the presence of ligand).
To do this, I am using OVERLA

Hello Navin,
what happens when you read them both into pointless, followed by
aimless? Once processed, the data should scale irrespective of the
2theta. If they don't they might be indexed differently, but pointless
would fix this.
Best,

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
Hello, Navin
Not enough information. What do you mean by "picking" up? Low I/s, high
Rmeas, too many "alien" spots? May be your crystals are twins with high
mosaicity, with ice rings and high background noise.
Please, share your processing log file (Mosflm?DENZO?)
Some home sources have additio
I thought imosflm recognizes automatically the 2theta offset ?

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 w
Hi Navin
I'll assume you are using iMosflm from the CCP4 suite. Have you tried
increasing the resolution in the "Processing Options" window, under
the "Processing" tab?
The option to display resolution rings and change the resolution by
"dragging" the ring does not work at present in iMos
Navin,
You mean that you can not PROCESS your data set? What diffraction data
processing program are you use?
What is your source, goniostat, diffractometer, area detector?

Hello everybody,
i am a freshman in structural biology. Right now i encountered two questions
and need help from all of you:
1) from the paper, i saw there are three different interactions between the
ligand and the residue:(i) hydrogen bonding, (ii) π–π stacking and (iii)
cation–π interactions,
This paper compares the activity of various proteases (Prescission is GST
tagged HRV 3C) in detergents; PP should be active in DDM.
