Re: [ccp4bb] electron microscopy: where open access fails

Dear Filip, CCP4BB, 3DEM, and PDB-L list members,

Thank you for your enthusiastic showing of community support for mandatory 
deposition of cryoEM maps to EMDB and for their timely release.

The two year hold is available to EMDB depositors for just one practical 
reason:  it encourages deposition of maps that we would probably otherwise not 
be getting at all (and those experiments would thus never be falsifiable).  
Until journals and major funding agencies make deposition and immediate release 
mandatory, we have to compromise.   A large number of petition signatures ( 
http://www.petitiononline.com/cryoEM/petition.html ) will certainly help us to 
solidify our case. 

It is easy to forget that it was not until 1989 (17 years after the PDB began 
collecting X-ray structures) that community-set guidelines were published for 
X-ray crystallography coordinate deposition, and several more years before the 
journals required deposition as a prerequisite for publication.  Structure 
factor deposition only became mandatory in 2008. These policies emerged from 
cooperative action by the community of experimentalists and interestingly 
included a petition that was led by Fred Richards. The same process will be 
effective for the EM community.

Sincerely,

The EMDataBank.org team

The EM Databank (EMDB, http://www.emdatabank.org/) is a resource for the 
archival deposition and retrieval of EM maps and associated metadata. It was 
established in 2002 by the European Bioinformatics Institute (EMBL-EBI, UK), 
and is now run jointly by EBI, the Research Collaboratory for Structural 
Bioinformatics (RCSB, USA), and the National Center for Macromolecular Imaging 
(NCMI) at Baylor College of Medicine. 

Following the model of the wwPDB, development of EMDB policies and procedures 
is community-driven. The resource is advised by a panel of leading experts. 
This fall, an Electron Microscopy Validation Task Force (EM VTF) will be 
convened to make recommendations as to how best to assess the quality of both 
maps and models that have been obtained from cryo-EM data.  Its recommendations 
will form the basis for a validation suite that will be used for maps and 
models deposited in the appropriate databases (EMDB and PDB).

As seen by the history of the PDB, journal requirements can greatly influence 
data deposition. For articles reporting the results of electron microscopy 
studies, the rate of EM map deposition is higher for journals that have 
well-defined and consistently-enforced policies than for journals without 
deposition requirements.  We have recently contacted journals that publish EM 
studies to encourage them to include a deposition policy for EM structural data 
in the instructions to Authors, and we are continuing to follow up with them.

Currently, depositors may choose to release deposited data immediately, upon 
publication (selected by the majority), after 1 year, or after 2 years. The 1 
and 2 year holds are intended to encourage EM scientists to deposit maps by 
providing a time period in which they can perform additional studies/analyses 
before the map is made public.  Based upon community feedback, the option to 
hold a map for 4 years was retired in 2008.

Dear Cathy/EMDATABANK team:

It is hard to comprehend the option for keeping maps on hold for up to 2
years.  It seems any depositor would do this for pure selfish reasons: keep
the data to themselves, don't allow anybody to verify the data for a long
time, and have the exclusive right to do experiments with the maps. For
example, this would allow the depositor to be the only one perform docking
experiments with any partial crystal structure for 2 years, and also these
experiments wouldn't be falsifiable for a period of 2 years (!).

Comparing this with crystallography: one would keep a crystal structure of a
good drug target 'on hold' for 2 years, thus not allowing anybody to use it
to start rationally designing new drugs (the success rate aside for this
matter).

In scientific terms, two years is 'huge'.  It is in this time frame that a
new theory can be postulated by one, and then shot down by ten other papers.
 It is 40% of the time frame of an NIH ROI1 grant, and 66% of a typical
Canadian CIHR grant. When it comes to cryoEM and crystal structures of
important therapeutic targets, delaying the field for 2 years will ultimate
cost lives.

In the end, journal editors should create firmer and waterproof policies
like those implemented for crystal structures, such as not allowing
publication until the data are in the 'hold for publication' status. Some
journals already have the clear policy of requiring deposition of the cryoEM
maps, but the 2 year hold is currently a big loophole.  Many more journals,
however, don't require the deposition of maps at all.  Of course it would
help if the EMDB didn't allow for these loopholes...


Sincerely,

Filip Van Petegem

Dear crystallographers,

For those of you who have shared personal frustration with cryoEM map
availability, or for those of you who would simply like to see science
proceed as it should, here's your opportunity to sign an on-line petitition.

Please feel free to send the link below to any of your colleagues. More

[ccp4bb] electron microscopy: where open access fails

2010-05-18 Thread Filip Van Petegem
Dear colleagues,

whereas data sharing for most crystallographers appears to be a no-brainer,
making coordinates and (most of the time, hopefully) structure factors
available, it seems the electron microscopists are drastically lagging
behind when it comes to making data available.

Many cryoEM structures are still being published without the corresponding
maps being deposited in the EM database.  In one particular case, I was
interested in looking at a cryoEM map from a paper published in a
well-renowned open access journal starting.  The paper contains the EMDB
accession codes for the maps, but these maps appear to be 'on hold' since
over a year.  Enquiry with the authors delivered a firm 'no' in releasing
the maps:  they claim it is OK to keep the maps on hold for 2 years, simply
because the EMDB gives the option to do so.  A further enquiry with the
journal editors led to no avail: despite the clear journal policy on sharing
both manuscripts and data, they were also unable to force the authors to
release their maps, now ~13 months after publication of the paper.  The fact
that this was in an open access journal makes this all the more shocking.

It is striking to see how much still has to be done to lift the cryoEM world
up to the same standards as the crystallographic community (when it comes to
sharing data, at least). Structures can simply be published without anybody
being able to check the validity, let alone use it for obvious experiments
such as docking crystal structures, integrative protein structure modeling,
etc.

With many structural targets going towards bigger and more challenging,
combining cryoEM data with crystal structures is going to become more and
more important. What can we, crystallographers, do to stimulate
data-sharing in the cryoEM world?

(My apologies to the cryoEM people on this bulletin board:  if you have been
making your maps available, you'll agree that clearly not everybody does...)

Re: [ccp4bb] electron microscopy: where open access fails

2010-05-18 Thread Bernhard Rupp
When X-ray crystallographers not so many years ago thought they are the

salt of the earth, of science and then some (well, some believe so

to this date), the same attitude prevailed (data holds). Once every

person with access to Google does it, that secrecy slowly disappears.

 

What also helps is a few major fups, which promotes community

response by those who have nothing to hide. Fups tend to happen at the

transition from expert science to Google science. EM is probably not there
yet.

So, talk to you colleagues, question every structure, and make the 

argument that science without data is non-falsifiable in Popper's sense 

and thus en par with quackery and superstition.

 

That should make you a lot of friends (or at least it will draw a 

response).   

 

Cheers, BR
