Hello,
The information you provided to us here is not enough. there are so many
parameters and
so many means to optimize 2D crystal. All of which depends on what kind of
protein you
are working on (membrane associated or soluble) and what kind of technique that
you use
to grow your crystal (l
I am equally upset by the fact that citations in the supplementary
material tend not to get into the citation indices, though it is
not quite so bad for SHELX because it tends to be cited in less
prestigeous journals that make less use of supplementary material!

I've been compiling a reference database and I've just noticed that it's quite
difficult to automatically retrieve references for most articles on
crystallographic software. Has anyone noticed that? It seems that, for some
reasons, articles on the "Computer programs" section on Journal of Applie

I believe that the first publication to report the use of coefficients 2Fobs-Fc
antidates both the Main publication and the use of a downweighting of the Fc
and is in Freer, et al., 1975 J. Biol. Chem. 250:46-54, which also gives a
heuristic account of the value of such coefficients.

Update your refmac? The latest refmac seems to have 200 rather than 70,
but I'm not sure when it was updated.
If that is not enough, you need to change MAXTLSGRP in tls.fh and
recompile.
Do you need so many? You might. But I also see cases where the TLS model
is much more detailed than necessary.
Please pay attention to this version of the message regarding the call
for abstracts 2009.

Hi Ian,
Indeed, I didn't have time to reply during the festive season.
Just to give appropriate credit, the 2mFo-DFc coefficients for
acentrics in SIGMAA were derived by analogy to arguments made by Peter
Main, but taking account of the effect of errors in the partial
model. According to

Dear Phil & CCP4ers,
to my knowledge, none of the existing reciprocal-space refinement
programs is really suitable for low-resolution refinement. In my
opinion, what is clearly missing, are automatic hydrogen-bond-
restraints that would stabilize all secondary structures and other
