Dear all,
does anyone experience a problem viewing refmac results with Log Graph?
The window appears and disappears in less than one second and this is the
output on the terminal window:
Error in startup script: syntax error in expression 10 11 12 + 12: extra
tokens at end of expression
This is fixed now if you re-install updates and
Armando - this is crude but if you edit the log file and replace
Rfactor v. resln :N:1,6,7 11 12with Rfactor v. resln :N:1,6,7,11,12
it will work.

Dear Remie,
the R-factor is a complicated thing that depends on things like
weighting factors and solvent model - several things that are not part
of your model and that need to be adjusted by the refinement program
during refinement.
That's why I
Dear all,
kind reminder for PhD fellowship opportunities at the International PhD program
of the IGBMC, notably for Integrated Structural Biology.
Deadline for applications is 3rd of june 2014: http://phdprogramme.igbmc.fr/

Hi Thomas,
I too would use the data out to 2.55A, as you did. The main point is that the
2.45A model produces a worse Rfree (30.16%) at 2.55A than the 2.55A model does
(30.03%). And this tendency is confirmed for the 2.35A model, so there's no
point in going beyond 2.55A.
best,
Kay
An obvious point - remember refinement exists to give you the best possible
model so you need to look at the maps.
And I guess that has to be a subjective assessment - if you SEE anything
more clearly at the higher resolution - I would use that data, but if the
maps do not improve discard it..
Dear V.
are you sure these are crystalline? - I have had similar growth from
'spherulites' that I thought was promising. But then when I went in with a
needle to break them for seeding, it turned out they were fibrous not
crystalline. This made me think they were a product of denatured
Hi Venkat,
I think there are maybe a few things you could do.
- Have you tried to lower the concentration of your protein? Maybe these
clusters appear like so because there is little time for better ordered
growth. If you decrease the protein concentration, supersaturation will
occur slower and
Dear All,
I experienced an odd observation with some philosophical consequences (here
we go again)
When I run a model obtained from a perhaps popular but until further
examination unnamed server,
and validate through coot/validate, the model kills probe/reduce which
normally works great.
Thank you very much for useful suggestions! :-)
Best,

Dear Almudena,
if you follow the recommendations given in the Difficult datasets
article on XDSwiki, your problem would have a good chance to be solved.

Hi Bernhard,
I am not sure this represents your problem: when I only select the
ATOM cards and of those only columns 1-56

the molprobity server has no problems analysing this file including

CCP4 refinement file is showing warnings that the Glc units are at distance

other even though I got the model from a published pdb file. so the pdb file
generated only shows me

Dear All,
a question about C2 and I2 space groups.
Processing a dataset, XDS output says C2, with dimensions 122.8, 56,9 81,5 and
beta 125.1°.
Aimless reindexes to I2 with 81.6, 56.9, 101.1 and 96.2°.
Phenix (refine) returns a warning NOTE: non-standard setting used: I 1 2 1.

Hello folks,
I would like to measure the concentrations of proteins containing
phosphotyrosines using absorbance at 280nm.
I'm wondering about calculating extinction coefficients by the Edelhoch
method - as used in ProtParam for example:

If you do not specify that you prefer C2, pointless change to I2. This is
sometimes odd, for instance when running molrep or shelx (hkl2map) afterwards

I previously used an extinction coefficient of 600M-1cm-1 for phosphotyrosine

I2 and C2 are different settings of the same group. The official IUCr
convention is to use the one which gives the beta angle closer to 90 degrees.
As far as I know all programs should now be able to use the I2 setting, but if
it worries you, you can reindex to C2
