Macromolecular crystallographers are (or should be) well aware that peaks that are remote from the main regions of electron density should be looked on with suspicion. They probably represent errors. Fortunately, this does not apply to places where crystallographers are to be found, as otherwise New Zealand would have long ago been removed from the map! So would other small groups of geographically-remote crystallographers. These thoughts came to me while attending the 3rd meeting of the Asian Crystallographic Association in Kuala-Lumpur; in fact, this letter is written between sessions. Some of the countries of the Asian region have long and rich tradition in crystallography, but others do not. Many of the crystallographers here have long distances to travel, and face extreme difficulty in finding travel money, yet there is great talent and enthusiasm that is very important for the future. There are exciting developments under way, including new instrumentation and new synchrotron facilities and the challenge is to see that all can benefit.

Our General Assembly and Congress, the next of which is to be held in Glasgow in 1999, is the culmination of each 3-year period. The meetings of the Regional Associations fill a different, but equally important role, however. They enable people to meet who share similar problems, or might benefit from closer ties and they provide opportunities to develop ways of sharing and utilizing regional resources. They also give confidence and encouragement to crystallographers from far-flung parts of the region. These comments could, of course, equally apply to other regions such as Africa, South America and some parts of Eastern Europe, and I applaud the moves of the American and European Crystallographic Associations to widen their horizons. I would also like to have the IUCr do more to help crystallographers attend such meetings - not only young scientists, but also those more senior scientists who are struggling with great determination to develop crystallography in their own environments.

Core CIF Dictionary This dictionary provides CIF names and definitions for the basic crystallographic concepts, particularly those needed for single crystal studies of simple materials. It is the dictionary that is used for most papers submitted to Acta Cryst. C. CIF_core.dic 2.0, the currently approved version, can be found at http://www.iucr.org/iucr-top/cif/cif_core. CIF_core.dic 2.1 is in preparation. Members of the coreDMG are: I.D. Brown (Chair): idbrown@mcmaster.ca, B. McMahon (Secretary): bm@iucr.org, P. Edgington, H. Flack (Consultant), Y. Grin (Consultant), S. Hall, G. Madariaga (Consultant), G. Sheldrick (Consultant), T. Spek, J. Westbrook (Consultant). The coreDMG discussion list can be viewed at: http://www.iucr.org/iucr-top/lists/coredmg. Powder Diffraction CIF Dictionary This dictionary has been designed to provide the necessary items for describing powder diffraction results. It is now being used for the submission of Rietveld refinements to Acta Cryst. C and has been adopted by the Int'l Center for Diffraction Data for use in future versions of the Powder Data File. CIF_pd.dic 1.0, the current version, can be found at http://www.iucr.org/iucr-top/cif/pd Members of the pdDMG are: B. Toby (Chair): Brian.Toby@nist.gov, L. Cranswick, T. Degen, B. von Dreele, J. Faber, A. Fitch, J. Rodriguez-Carvajal. The pdDMG discussion list can be found at http://www.iucr.org/iucr-top/lists/pddmg. Report from COMCIFS Now that three basic Crystallographic Information File (CIF) dictionaries have been approved, COMCIFS (the IUCr Committee for the Maintenance of the CIF Standard) has completed the first phase of its work. The new terms of reference, recently approved by the IUCr Executive Committee, can be found at the URL: http://www.iucr.org/iucr-top/cif/comcifs/terms.html. In the past five years, the business of COMCIFS has been carried out by email in the form of eighty-five circulars distributed to its members. All these circulars can now be viewed at http://www.iucr.org/iucr-top/lists/comcifs-l. Since Sept. 1998, COMCIFS has conducted its business using a discussion list (archived at the same address). Only members of COMCIFS may contribute to this list directly, but anyone is free to view the discussions and to send their comments to the coordinating secretary (bm@iucr.org) for inclusion as appropriate in the discussion list. Maintaining the three CIF dictionaries has tended to distract COMCIFS from the more central matters of philosphy and policy. Therefore COMCIFS has set up Dictionary Maintenance Groups (DMG) for each dictionary. Each of the DMGs, which are responsible for recommending changes to their respective dictionaries, archives its own discussions and these may be viewed at the URLs given below. Everyone is welcome to review these discussions and to contact the appropriate DMG with suggestions or corrections. This arrangement should allow the dictionaries to respond rapidly to the needs of the community. Macromolecular CIF Dictionary This dictionary is used for reporting macromolecular structures and has been adopted by the Protein Databank and Nucleic Acid Databank. The latest approved version, CIF_mm.dic 1.0, can be viewed at http://ndbserver.rutgers.edu/NDB/mmcif/dictionary/index.html, mirrored at http://www.iucr.org/iucr-top/cif/mm. Version 2.0 is in an advanced stage of preparation. Proposed amendments can be found on the mmCIF mailing list. Members of the mmDMG are: P. Fitzgerald (Chair): (paula_fitzgerald@ merck.com), H. Berman, H. Bernstein, J. Westbrook, with an editorial board consisting of F. Allen, P. Bourne, K. Henrick, A. Howard, J. Sussman, D. Tronrud. The mmDMG has a public mailing list at: mmciflist@ndbserver.rutgers.edu , which is archived at http://ndbserver.rutgers.edu/NDB/mmcif/resources/mail/index.html and at www.iucr.org/iucr-top/cif/mmcif/ndb/resources/mail/index.html All of the dictionaries and the discussions of the various committees can be accessed from the IUCr home page: www.iucr.org/iucr-top/index.html.

Its Good to Talk The IUCr announces a new discussion-list service as a means of stimulating written discussions amongst crystallographers on topics relevant to the IUCr and the field of crystallography. The discussion lists are complementary to the other information services (print and electronic) of the IUCr. The printed quarterly IUCr Newsletter and the electronic web services (http://www.iucr.org/iucr-top/) are provided by the IUCr for the dissemination of information to a very wide and unrestricted circle of subscribers. On the other hand the discussion lists are provided for smaller groups interested in or working together on specific topics. They are ideal for IUCr Commissions, sub-commissions, committees, working groups and other bodies. Lists already exist to serve the Electronic Publishing Committee and various groups working on the CIF project. Others may be requested under the terms of the policy document at http://www.iucr.org/iucr-top/lists/policy.html. Discussions are archived and made available through public, searchable web pages. The IUCr will offer these archive and search facilities to other suitable lists maintained elsewhere. For further details consult the web pages at http://www.iucr.org/iucr-top/lists/ and mirror sites, or send an email inquiry to bm@iucr.org. Brian McMahon, IUCr, Chester Executive Committee meets in Arlington At its meeting in Arlington, the Executive Committee discussed the handling of Special Issues in the IUCr journals. Special Issues confirm the importance of different communities to the IUCr and encourage these communities to subscribe to the IUCr journals. However, the production of fully refereed and technically edited Special Issues is expensive. In addition, the effect of the extra workload on the Chester staff is reflected in increased publication times for all the journals. The Executive Committee therefore endorsed the recommendation of the Finance Committee that Special Issues should be considered in two categories. The first category relates to issues on special topics in crystallography, which, because of their timeliness and importance, would increase the impact of the journal. Usually these would result from initiatives through the Commission on Journals. The Fiftieth Anniversary Special Issue of Acta A (Nov. 1998) is a good example of such an initiative. Special Issues in this category will be produced in-house as regular journal issues with a strict limit on the number of pages allowed each year. The second category is Conference Proceedings that will be handled as camera-ready copy after full refereeing. This would create a minimum of extra work for the Chester office and significantly reduce cost. The first such Special Issue, the Proceedings of the 10th International Conference on X-ray Absorption Fine Structure (XAFS X) (Chicago, IL, USA, Aug. 10-14, 1998), will be published as a Supplement to the Journal of Synchrotron Radiation in 1999. Among the many other items discussed were: ·Development of the IUCr web site and provision of online journal services (Acta D is scheduled to go online in 1998 with the other journals following in 1999); ·The work of the recently appointed Promotions Representative; ·Fiftieth Anniversary celebrations; ·The Glasgow Congress arrangements and Programme; ·An initiative to promote crystallography in Africa involving greater use of the IUCr Visiting Professorship Scheme.

Macromolecular CIF Dictionary The following remarks were made by Carmello Giacovazzo, first president of the European Crystallographic Assn, at the opening ceremony for the 18th European Crystallography Meeting in Prague, Czech Republic. -ed. It is a great honor for me to extend a welcome to the participants in the 18th European Crystallographic Meeting on behalf of the European Crystallographic Assn (ECA). The ECA was formally established in 1997 at the Lisbon meeting. It is the successor to the European Crystallographic Committee which had guided the development of European Crystallographic meetings from their inception through the Prague meeting. The European Crystallographic Assn arose from the conviction that a stable and well organized association can do much more for the development of European Crystallography than a committee simply charged with organizing the European Crystallographic meetings. Among the objectives of the association are: to contribute to the advancement of crystallography, to promote European cooperation in crystallography, to organize meetings and conferences, to promote crystallographic research requiring European cooperation, and to organize special projects These objectives can be attained only if we are able to establish a home for all European crystallographers, where all the scientific areas can find the maximum of freedom, respect and opportunity. This has been a busy year for the Executive Committee and Council of the ECA. The first achievement has been the approval of the statutes: the defining document for the Association. We now have guidelines to follow for future activities. We also started an electronic newspaper called ECA News, available via the Internet. The aims of ECA News are to establish direct and rapid contact among ECA Council members and the entire Crystallographic Community to serve as a vehicle for open discussions about new ideas and themes of common interest and to future ECA activities. We urge you to read and contribute to the ECA News. The ECA has established Special Interest Groups (SIG's) to organize microsymposia at future meetings that have wide ranging authority to organize meetings, schools and workshops in their area. The first SIG's were approved in Prague, and several others are in development. I invite people to look at the ECA News to see how to join existing SIG's and form new ones. The IUCr has officially recognized three regional associates: American, European and Asian Associations. It is obvious that at this time the European Association should represent and recognize, in addition to crystallographers in Europe, also those in Africa and the Mediterranean as full members of the ECA. We look forward to a wider membership by African countries. A flourishing ECA will be vital to the future of the IUCr. Carmello Giacovazzo
Crystallography in Novosibirsk 40 years ago, G.B. Bokii, a corresponding member of the Russian Acad. of Sciences, established a crystal chemistry lab in the new Institute of Inorganic Chemistry, Novosibirsk. Today the lab completes over 40 crystal structures yearly. These include metal oxides (R.F. Klevtsova and S.F.Solodovnikov), transition metal complexes with organic ligands (G.V. Romanenko and N.V. Pervukhina), natural and modified zeolites (V.V. Bakakin) and chalcogen-containing metal carbonyl clusters (N.V. Podberezskaya and A.V. Virovets). Other studies concern analysis of crystal-forming factors including formation conditions, phase transformations, packing regularities of complex coordination compounds (N.V. Podberezskaya), and close-packed atomic nets and sets ordered via a system of elastic planar standing waves (S.V. Borisov). A study is in progress on volatile compounds that form mono- and melting layers on crystalline substrates. Perfectly oriented polycrystalline films are obtained for some compounds and conclusions concerning the structural organization of the layers (I.A. Baidina and S.A. Gromilov). We also maintain a database of "Inorganic Crystal Structures", with emphasis on technical materials (S.A. Magarill). The work of the lab forms a significant part of the contents of the Journal of Structural Chemistry published by the Inst. of Inorganic Chemistry.

Advances in Australia Small Angle and Surface Scattering Australian facilities for small angle X-ray (SAXS) and neutron (SANS) scattering and reflectometry are expanding. Forty scientists whose interests ranged from biology through chemistry, physics and materials science to engineering attended the first small angle and surface scattering meeting held at the Australian Nat'l U. (ANU) in April 1998. These techniques are used to examine the detailed structure of condensed matter on scales from about 1 to 100 nanometers, in the supramolecular nanostructure range. By use of isotropic substitution or tuning the wavelength it is possible to selectively highlight different components in bulk materials and all types of surfaces and to follow chemical reactions and microstructure and texture formation at a scale inaccessible to ordinary microscopy or light scattering. New instruments now available include an X-ray reflectometer at the Research School of Chemistry; two more SAXS machines at ANU and the U. of South Australia; and a SAXS/Grazing incidence X-ray diffraction on "BigDiff" at the Australian Nat'l Beamline Facility, Tsukuba. Applications from the area of materials included studies of templated mesoparticles silicates, titania/zirconia nanoparticles, composite films of silica and organic surfactants, colloidal silica, and quantum well semiconductor devices. More direct applications to petroleum geology, domains in wood pulps, and activated carbons for water treatment were presented. The meeting left a clear impression that with the new apparatus these techniques can provide a new view of structure in a range in the past thought too large for chemistry but too small for engineering. (Philip Reynolds) SKETCHES OF AUSTRALIAN LABORATORIES St. Vincent's. The Protein Crystallographic Unit at St. Vincent's Inst. was founded by N. Isaacs in 1978. While at St. Vincent's, Neil solved the structure of a "goose-type" lysozyme and crystallized human chorionic gonadotropin, a hormone involved in early pregnancy. In 1991, the appointment of M. Parker as Head of the Unit was supported by the Wellcome Trust. The Unit was renamed The Ian Potter Foundation Protein Crystallography Laboratory. It is well equipped with a Riguku RU-200 rotating anode generator, two MAR-research image plate detectors and cryo-cooling equipment from Oxford Cryosystems. The lab has been fortunate in attracting talented postdoctoral fellows including M. Wilce, B. Kobe, J. Rossjohn and S. Feil. The lab has concentrated in three major areas of biology over the last seven years; membrane-interacting proteins, detoxifying enzymes and protein kinases. Particular highlights include the structure determinations of aerolysin, prefringolysin O, twichin kinase and various glutathione transferases. (M. Parker) University of Canterbury. The U. of Canterbury Chem. Dept. upgraded a Siemens P4 diffractometer to a SMART CCD system at the beginning of May 1997. Making it possible to gather two data sets every 24 hours. The SMART is heavily used for wood fibre diffraction determining the preferred orientation of cellulose crystallites in timber. This industrial application has proved both interesting and lucrative. There are many fascinating potential applications in studying powder diffraction in almost real time. (W. Robinson) Monash University. A new macromolecular X-ray lab is being setup at Monash U. following the appointment of O. El-Kabbani. A Rigaku RU-300 rotating anode with a MAR-345 image plate detector system and a Oxford cryogenic low temperature system and an SGI 02 workstation. (O. El-Kabbani) University of Western Australia. The two new area-detector diffractometers at the Crystallography Centre at the U. of Western Australia were officially "blessed" on Wednesday, July 29,with a gathering of financial backers. The BRUKER Smart1000 AXS has been collecting 140 data sets per month and a MAR345 Image-plate system has been installed and tested. At this opening science-fest S. Hall, A. White, V. Streltsov and M. Wilce outlined future activities of the Centre in their respective areas. M. Wilce heads the macromolecular effort and holds a joint appointment with the Crystallography Centre and the Dept. of Pharmacology where he has facilities for bacterial expression, purification and crystallization. Matthew's macromolecular group will be studying an integral membrane protein - mechanosensitive channel protein, protein/DNA complexes and complexes of sub-units of ATPase. (S. Hall, M. Wilce).

Web Pages on BCA Site for
The scope for in situ diffraction experiments has increased enormously over recent years as more intense sources of X-rays and neutrons have enabled experiments to be carried out on smaller samples or faster transformations, or in environments with poor access to the probe. Pannetier and his colleagues are studying chemical and structural changes that occur inside a solid-state battery as it discharges and the cell reaction proceeds. Neutron diffraction provides a direct probe of these processes in real time in the chemical environment most relevant to the problem. A web page is being set up on the BCA web site to provide an information source on techniques and facilities, areas of activity and practitioners, for experts and would-be users. A. Harrison and K. Crennell are setting up a draft page at http://gordon.cryst.bbk.ac.uk/BCA/insitu/index.html. The page will focus initially on activities in the UK, concentrating on neutron diffraction and X-ray techniques, with links to the more specialized information held at the CLRC Lab by the ISIS Facility and the SRS Daresbury. In the future, the scope of the activities and practitioners will extend beyond the UK and may also include other structural probes such as EXAFS. Contact A.

It's in the Bank There are currently over 400 completely sequenced organisms in GenBank, including 378 viruses, 16 bacteria, Saccharomyces cerevisiae, and a number of plasmids and organelles. Nat'l Ctr for Biotechnology Information (NCBI) makes these available in a variety of ways to accommodate the needs of the scientific community. NCBI has collected preliminary sequencing data on 18 microbial genomes and has made these data available for BLAST sequence similarity searching as part of the BLAST service at http://www.ncbi.nlm.nih.gov/BLAST/. from NCBI News July '98 User Fee for Protein Database Plagued by a funding crunch and inundated with new data, SWISS-PROT, a widely used amino acid database, will soon start charging a fee to industrial users. SWISS-PROT contains sequences and other information on more than 70,000 proteins and is used by some 200,000 researchers in 100 countries, according to its developer, Amos Bairoch of the University of Geneva. But managers have a back-log of about 150,000 computer-generated sequences from which to winnow out protein information, and the database's $3 million-a-year budget is only half of what it needs, he says. N. Williams & R. Stone (July
'98 Science) Electron Crystallography Database S. Hovmöller and T. Weirich have set up an Electron Crystallography Database, at Stockholm U. for images and datasets for use in teaching, for testing new theories or algorithms of image processing/simulation etc. The database will be freely accessible through the Internet, and everyone can submit information. All datasets submitted are to be free for anyone to use, provided acknowledgement is given. Alex McPherson |

Gold in them there Structures Data Mining in Crystallography, the 29th Crystallographic Course at the "E. Majorana" Centre, Erice, Italy to be directed by T.L. Blundell (Cambridge, UK) and S. Fortier (Kingston, Ontario, Canada) May 12-23, 1999. Data mining deals with extracting useful information, such as general rules and patterns, from large databases. With the rapid growth in scientific databases, it is essential to be able to synthesize, organize, compare and understand the information contained in databases so as to achieve the transition from databases to knowledge bases. With readily available electronic communication channels, the databases have become universally accessible and prime for exploitation. The need for computational tools to assist in data mining processes is pressing. Crystallographic databases were established in the 70's for proteins (PDB, Brookhaven, USA), organic and organometallic compounds (CSD, Cambridge, UK), inorganic compounds (Karlsruhe, Germany) and metals (CRYSTMET, Ottawa, Canada). The school will explore the methodological advances needed for effective and efficient data mining in the crystallographic domain. The application of these methodologies to drug design, protein structure prediction, genomics and materials design will highlight the discussions. The meeting will bring together researchers from the areas of crystallography, informatics and machine learning for in-depth discussion of topics which will include: a) Fundamental concepts; b) Methodologies and tools; c) Major applications; and d) Biotechnology and bioinformatics Speakers include: F.H. Allen (UK), H. Berman (USA), P. Bourne (USA), G. Desiraju (India), J. Glasgow (Canada), G. Klebe (Germany), R. Lathrop (USA), L. Leherte (Belgium), C. Orengo (UK), D.C. Rohrer (USA), A. Sali (USA), J.L. Sussman (Israel), D. Vercauteren (Belgium) and S. Wodak (Belgium). Applications should be mailed (or e-mailed) by Nov. 30, 1998 to P. Spadon. For further information contact: P.
