Thank you for the quick reply. After molecular replacement , i have done
only few cycle of refinement in refmac. I have not done any solvent
modification or NCS averaging. I have initially indexed the data in C2221
but Rfree was not decreasing so i reindexed the data in data in P121 space
group
Dear ccp4bb members,
I would be most happy, if you could point me to any publications, in
which results of crystal annealing by warming up a
DNA/RNA/oligonuculeotide crystal and again cooling it down to low
temperatures were reported. I am aware of 2 publications that discuss
this for
I run the phenix.xtriage to evaluate the twining but it suggest no twining.
When i reindex from C2221 to P21, the completeness of data reduced from 95
% to 35% whereas the map is very good and Rwork and Rfree are 26/31 for 2.2
resolution. I do not understand why the completeness of data reduced so
Chris, indeed nanoITC instrument analysis software is very robust and user
friendly (probable more friendly than microcal, GE).
Although when you need to subtract Q (heat) values (from 2 or 3 blank
experiments) from your experimental data you cannot. NanoITC software can
subtract Q values
Hello,
Here we deal with symmetry and the unique part of reciprocal space (the
reciprocal space asymmetric unit so to speak).
C222(1) has eight asymmetric units (international tables, space group 20);
P2(1) only has two. Assuming that Friedel's law does apply, then the
minimum rotation
Hi guys,
I need to manually build a model in Coot without a map. I want to link to 2
loops from 2 DNA strands together by base-pairings while keep the rest part
as freezing as possible. The sequences of the loops are complimentary but
the current orientations of the loops is not correct. Is there
Dear Appu,
You want to be sure you have good reason to drop the space group from
C222(1) to P2(1). There may be many reasons why your Rfree may not drop
following refinement, especially if you only have one domain in your
protein located and just in case there are more molecules to locate in the
Sorry for the misconception. Yes i am expanding the space group from merged
mtz file. Actually i have enough number of images collected. when i
indexed, integrate, and scale the data in either C2221 or P 21, it fetches
the overall 98% completeness. But when i am trying to reindex the data
from
Hi George,
this is probably a very stupid suggestion and you likely have tried it, but
I'll suggest the obvious nevertheless.
What happens to your .nitc file when you rename it to .itc can you read it in
Origin then ?
