Re: IUCr congress - CompComm nominations and suggested symposia -

[spea@chem.uu.nl (a.l.spek)]

Dear Lachlan,

How was the Siena meeting ? Anything interesting to report on ?

Our meeting in Leuven went well. I already mentioned the 'charge
flipping' technique in Siena. In Leuven it became clear to me that this
new method to solve structures is very promising. The method was first
reported by Gabor Oszlanyi & Suto in 2004 (who was also a speaker in 
my session). It now turns out that the method is also used successfully
to solve powder and incommensurate structures.

So, coming back from Leuven, I massaged the tools that are already in
PLATON for SQUEEZE into a tool named FLIPPER to implement charge
flipping. And indeed, the method solves structures from scatch without
previous knowledge of the spacegroup (a job for ADDSYM afterwards). 
The UNIX implementation is on the WEB. Louis Farrugia is working to
get things working under Windows as well. (Louis is currently
handicapped with a broken leg and forced to stay at home).

> For the request of the XXI Japan IUCr Congress for CompComm reps on
> the international program committee:

This was on my list 'to do' to contact you on. I did not know that you
received similar requests.

I would think that you are the best person to represent the committee
in Japan. I hope that you can accept. 

I do not think that I know Izumi. Is he involved in computing ?

As for your suggestions for subjects:

I think that your suggestions are in line with my idea that there
should be a number of slots of the type you suggested for people 
doing software development etc.

I have not approached yet our Japanese member but will do this week.

What we need is an interesting covering theme.

Best wishes for now

Ton
