Dear all,
Does anyone know how to calculate the cell parameter of the 2-D protein crystal?
The map of the crystal can be found in this blog:

Dear all,
Thank you for your advices.
I had tried to use MPD and pyrophosphate etc to fix the density map but all of
them were too small.
We guess that the molecular formula should be C8H18O2. So we search this
formula in google and find two candidate molecules

Dear Yuan.
1. Is there any programs that could help to compare and check the heavy atom
positions in shelxd solutions? Especially in cases when the solutions are not
obvious. SitCOM seemed very good, is there a 32-bit distribution of this
programs? Or any others have similar functions?
If you u
Dear steffi,
Can you give me a link? I did not find it in google.
Thank you!

Dear all,
I have used CNS to calculate the experimental phase of my structure.
After Heavy-atom search, Heavy-atom refinement/SAD phasing and SAD Phasing -
Density Modification - Selection of Map.
Some files outputted:
sad_phase2.hkl
sad_phase2.sdb
density_modify.hkl
density_modify.map
density_mod
your final structure will be relative to the same
origin as your original
PDB file.
Best wishes, George

Dear all,
I want to do a statistics about the number of protein-protein complexes
deposited in PDB in recent years.(1972~1992,1993...2012)
I tried keywords "protein-protein complex", "protein complex" etc. in the
search of PDB but all of them are fail.
Can everyone tell me how to do?
Thank you v

When I used PHASER to do a molecular replacement and define ensemble via map

I tried many ways to generate the map file, but the results are the same.

Dear professor George Sheldrick,
I am so sorry to bother you again!
From the shelxc_fa.lst file, we can find that the Patterson peaks will be
selected only when the 'Mult' equal to 1..
shelxc_fa.lst:
Patterson (* indicates vector selected for search)
X Y ZHeight Mult
vy atom location. x,y,z are
the
crystal coordinates of the peaks, height is the peak height, mult indicates how
the
peaks have coalesced because they are on special positions (in Patterson space)
and length is the distance of the peak from the origin, i.e. the vector length.

Can everyone tell me the patterson peaks outputted by shelxd (see below) are
calculated by which formula and software?
Thank you very much!

Dear all
An ice ring is found in the raw image files and the resolution range is from
3.70-3.57A.
I want to remove this ice ring by excluding the reolution bin.
Can anyone tell me how to do?
Thanks a lot !
