Dear All -
if memory serves me right, the intersection curve of
a cone with a cylinder (like in a powder diffraction camera) is
not an ellipse, but a "Schnittfigur zweiter Ordnung",
loosly translated as 'intersection curve of second order'.
Is there a correct English term for that type of curve?
Hello All,
I'm trying to back-FT an EM map to produce Fs and phases to use in
molecular replacement, but am having a problem with running SFALL.
Here's the issue: When running the back-transform in SFALL (generating
structure factors from a map), I get the following error:
Incorrect sampling gri
Neural lace embedding is too barbaric. Has anyone written a coot
driver for this non-invasive alternative:

The superiority of thought driven building over dragging a mouse +
modifier keys might be reason enough to get me to switch from O.

Yes, it is down at the moment, due to a hacking event apparently. Don't know
any more.

use coot and select "expert" for specifying labels - it gives you a
choice for a anom diff map.

Sounds great.
You can jailbreak an iPhone/iPod touch and install a whole BSD
subsystem on it. So printing should be possible at some point...
This of course also suggests that iPod touch is a valid research
expense ...

Apologies for the slightly off topic post but can I draw people's
attention to the job advert below.

Another anecdote for you: I had crystals that grew in 15% PEG 2000 and
15% isopropanol. Cryos with glycerol melted the crystals. The best
cryo I found was with 15% PEG 2000, 15% isopropanol, and 20% PEG 400.
It's hard to predict how your crystals will behave with different
cryoprotectants-- hopef

Hi all,
Does anybody know what happened to the PRODRG server web site?

Not that all proteins are created alike, but we had a protein
crystallize in a similar situation (PEG/20%IPA). I don't remember the
exact details, but we did have good luck using just glycerol as a
cryoprotectant. That is, I made up the well buffer and added to that
well buffer 20-25% glycer

Dear everyone,
Has anybody tried to hook up a protein display/model building

games? The type of glasses where one obviates the use of large monitors
altogether, that is the display sits on the glasses themselves. Thanks,

The question is regarding the cryoprotectant.We have crystallized a protein
in 20% PEG 500 with 10% isopropanol.What should be the cryo we should try
for data collection.Also,what percentage of PEG 500 is sufficient enough as
a cryo for data collection.
