Dear all,

Let me start by apologizing for finally making this email longer than I 
intended - I did not have the time to make it shorter.

I must say I am humbled by the amount of positive energy and constructive 
thinking that Bill has. That must explain also how he manages to keep up a 
fantastic resource for the community, what is a largely thankless task with 
little academic reward, but still so helpful. His response did get me thinking, 
as his opinions often do. In principle, in an era of information sharing, why 
don't we indeed solve structures with the collective brain of world 
crystallographers? We could share data, and educate people, and also get better 
structures at the end of the day. As indeed many people are in a small 
institution somewhat off the beaten path - I work in a cancer research 
institute after all and I am the weirdo here - and as indeed I see my knowledge 
getting obsoleted in a steady pace, this idea sounds great!

However, its a bit like 'true' socialism - a grant idea, that we may find it 
will not work too well in practice, at least not under the constraints of human 
nature.

I will keep advocating the greatness of ccp4bb. Its a fantastic resource, which 
is made truly amazing by the many questions that are being asked, and keep 
educating everybody.
But, at the same time, I will keep advocating the usefulness of the typical 
constructions we have in science, whereupon people work in teams. These teams 
are there
to share experience and help each other with overlapping expertise. Why such a 
basic question (and others in the past) need to come out of the 'team'? 
Is there no competence within the team to address it, or is there no correct 
communication? 
In either case, should we as scientists encourage such teams with low-level 
competence? May I remind you that Tom is in Lueven/Belgium,
a large and outstanding University, with at least two very competent (and 
friendly) crystallographers in campus. Does the fact he has to post the ccp4bb 
with a basic question
testify for a complete failure of his supervisor to either help him or get 
other people on site to help him? Should such supervisors be left to guide 
students?

I have nothing against sharing data. I am the fool that submits data at the 
same time as I submit my paper, a practice that is followed by surprisingly a 
few people,
as most people wait a few weeks until the paper is accepted to submit their 
structure (some data mining shows that 1/3 of the PDB entries associated with 
papers
even in journals like Acta D are only deposited to the PDB at least a week 
after the paper submission date!.. no think what this % is in other journals). 
And the mild consequence of this is that somebody picks the structure up, 
panics to be scooped, submits his/her story, and scoops you  while your paper 
is being rejected 
for reasons that are not connected to the structure  (I am not implying foul 
play here, but suggesting a consequence of basic openness).

Are we finally, at the end, with this open and sharing spirit, encouraging 
people to think that crystallography is too trivial? It has once been said in 
this bb, that
'solving a structure is trivial in the same way that climbing mountain Everest 
is trivial: it has been down before, its being done now, and it will be done 
again,
by many well-trained and determined people'. Many people have read and trained 
for this task. If you do not read a couple of books and train before attempting 
the climb, 
and you send an email asking the everestbb 'does anybody know how to open this 
oxygen valve?' you are asking for trouble though 
… and the people that let you attempt the climb without that knowledge, are 
also in the wrong.

The end result of this open and sharing spirit, which downgrades the importance 
of competence in major methodologies like X-ray crystallography, 
was summarized recently is some text I recently got by email from Brussels:
 "... advanced methods for X-ray crystallography and Electron Microscopy is a 
very narrow field that will limit the employability of the graduates"
There are the wise words of the referees of a joined grant (with 10 other 
people from Europe) advocating to educate students to get an in-depth PhD-level 
training in crystallography and in EM. 

Maybe that explains my grumpiness. 
Or, as the crystallographer previously known as DVD mailed me in private 
"welcome to the club of grumpy old men". 
Maybe I am just being grumpy. 
Or I am justifiably worried.

A.

PS For the record I admire Tom's spirit and courage - he is the kind of guy I 
would hire for a PhD (not that he will ever want to work with me any more). 
I am less impressed by the team and his supervisors, as it stands, and without 
knowing all the details of what might be behind this.
