Dear CCP4BBers,
The find water option in coot is not picking up more that 10 water molecules
but density is there. How can it be sorted out?? Please help.
Thanks.

Hi Ed,
DISCLAIMER: When I say "grouped B-factor refinement" I mean CNS-style,
Bmain/Bside refinement. Not to be confused with more general "domain
B-factor refinement" where single B-factor is assigned to some part of
the structure.

Hi everyone,
Does anybody out there have a Grease Machine L-100 that they no longer use? It
can be broken or damaged, I just need to know what isn't working on it. I'm
trying to find spare parts to fix the machine I currently have. We can
negotiate on a price. Thank you,

James, I think the problem is that your simulation just doesn't contain
enough atoms in the unit cell with correlated displacements to exhibit
significant optic DS, i.e. with only 1 or 2 atoms it will be dominated
by Einstein-model DS which as I explained before is locally uniform and
therefore can
Those B factors probably mean the atoms are in the wrong place..

Hi Xun, i'm not sure if i have the best way of doing it, but i've used a

Frank, my point was that in the presence of DS (which for protein

There are a good many coiled coil models available. I suggest you search
the pdb for more models yourself, or let a program like BALBES do it for
you and do the MR searches as well.
IF you get a faint hit (usually marked by both R and rfree dropping a
few % on refinement) then Arp-warp or bucc
All I'm saying is that when I calculate the average general scattering
from 8192 random configurations of one disordered atom per unit cell:
