H..the real message from figure 3. The protein concentration.
seems to be that >70% of proteins do NOT crystallize in the 10-12.5 mg bin,
i.e. the 'right' concentration is an individual protein-in-that-buffer
property - and
all one can say is that the concentration needs to be high enough s

Dear Tim, Miguel
Thanks for your suggestions, the program does work now, but it seems that
it cant handle AnsioU s . It gives an error:
PDBSET: *** Anis
What about getting rid of the ANISOU records before processing the pdb
file, with
grep -v ANISOU input.pdb > output.pdb
?
If a program complains about ANISOU records then you use the isotropic
approximation...
That's what I would do as a quick and dirty fix.
Fred.

Dear Swastik Phulera,
unless you need the ANISOU cards, you can first remove them with e.g.
grep -v "^ANISOU" youfile.pdb > yournewfile.pdb
before running pdbset.
(I hope you don't work on a Windows machine, then you would probably
first find a way
In Windows:
findstr /b /v ANISOU input.pdb > output.pdb
Cheers,
Robbie

Dear Tim,Fred
Negative B factors and occupancies higher than one came in from shelxl,
Also getting rid of Ansiou at first would lead me to an additional step of
placing them in their right place later on (is there a short cut that I may
take).

If you are resetting B factors you must recalculate the AniosUs later
But if you are getting negative B values something in your procedure is
less than optimal!
Are you refining aniso Us with too limited data? You need high resolution
data to attempt this.
Are you trying to refine B factors and

Dear Swastik Phulera,
if your res-file sports negative U-values, your model has room for
improvement. You really should go back to the ins-file and make the
appropriate modifications in order to get rid of negative U-values

Bernhard,
I'm often amazed at how forgiving protein crystallization is, or to put it
another way, how efficient screens are at picking up crystallization hits
even when you do everything wrong.
However if you do go down to 20 + 20 nl drops you have to remember that
probably 3/4 of your protein wi
