Actually we don't declare anything to TSA, Jahaun just carries them in his
carryon and it is fine. Easy peasy?

Hi all
It’s been a while since I posted on this group so apologies for a slightly
tangential, non CCP4 question.
I wanted to get secondary structure predictions for designing a library of
50-100 amino acid peptides. The library could get very large ( 10^9) and I
was wondering if there is a way to

raising the 99*99 limit does not yet appear to be needed with a single such
machine - you'd have better performance by running XDS.INP with e.g.
MAXIMUM_NUMBER_OF_JOBS=4! number of processes spawned

Since Kay asks:
Do all of us really want and need to collect from thousands of crystals every
synchrotron day? Are all of us really producing that many crystals? Who is?
I can't help to respond: even if not "all of us", we certainly are!

Thank you for the info. Another of the Threadripper 3xxx series, the
3990X has 64 cores for 128 threads, so perhaps it is time to raise that
99*99 limit in XDS.

Dear Ana,

Back in the days when I worked with extremely oxygen and moisture sensitive
organometallics (some were pyrophoric given a sniff of oxygen...) I sealed the
crystals in capillaries under an argon atmosphere. The huge advantage of this
over shipping cryocooled crystals is that they can be packa
Dear Stephen
I guess the first thing to understand is whether you have a RT or cryo NMX
planned. In my personal experience the transition from RT to cryo NMX is not
necessarily straightforward. If you (and the beam line scientist) are sure that
cryocooled xtals will give you an experiment then

Dear CCP4 community,
I have an impending trip to a neutron source and was wondering how people tend
to ship their samples prior to beam time? Is sending something frozen best or
is sealed in a capillary more sensible or is there another better way? One
caveat is that ideally my sample should

To follow up on the contributions from others, there are some particular

imaging problems.
In tomographic reconstruction you have a big block of data which needs to (as a
