This nicely illustrates the danger of using too low resolution data to
compute the SRF (I'm referring to an earlier BB discussion on this
subject, where it was suggested to cut out the high resolution data,
against, it seems to me, all rationale). You should be using as high
resolution valid data

Thanks for the quick reply. I enclose the missing kappa=90 slice. It
is on the same scale as the kappa=180 slice. The log doesn't report
any peaks for the kappa=90 slice (using a 10 sigma cutoff). The unit
cell parameters are 104.63 104.63 109.80, 90 90 120 and based on the

Hi,
Hi all
I'm trying to understand why there is a peak that is perpendicular to
the c axis on my kappa = 180 and kappa = 90?
The chapter entitled "Characterizing a Crystal From an Initial Native
Dataset" from Sawaya says that R32 shouldn't have a central peak in
kappa = 180 nor 90.

Dear protein.chemist:
Try elbow.builder or phenix.elbow or whatever it is currently called.
It will optimize the geometry.
Good.luck

Dear All,
What is the best way to find the coordinates of a ligand.
I do not find teh ligand in Pdb.org. I am trying to draw it in prodrug but
the server is showing error.
Also if I draw it how do I make sure that the geometry is correct.
Thanks,
Mariah

Dear colleagues, please help me with a CNS syntax. In the refine.inp, I
could provide as many topology (or parameter) files as necessary:
{refine.inp}
{* topology files *}
{===>} topology_infile_1="CNS_TOPPAR:protein.top";
{===>} topology_infile_2="CNS_TOPPAR:dna-rna.top";
{===>} topology_infile_3
This sounds a little like multi-crystal averaging without the averaging.
If you were using the Uppsala program suite, you could perhaps do the
following:
[define one xtal as reference, the other as target]
1. Make mask in map grid for reference xtal (program MAMA)
2. Establish operator for r
Hi Rana,
You could use cphasematch to put the two maps on the same origin. To
do this you will need to CAD the two data sets together then give
cphasematch the phase columns to use. Typing "cphasematch" on the
command-line should tell you how to do this. It's a tool from the
clipper library, so th
COOT can help you.
If you have coordinates in both crystals COt can superpose the
coordinates ( LSQ superpose) and carry the density with the coordinates.

Hi,
I have two maps from two different crystals with the same space group, both
show an unknown density in the same place. I wanted to superimpose the maps
to see if it is the same/similar density.
Any ideas how to do this ?
Thank you,
Regards
Rana
