Dear All,

    Some of you may have already received application forms for the next CCP4 
Study Weekend. If not they may arrive soon, apologies to those who thought 
they were getting one and did not. Below is the blurb on the next meeting and 
application forms can be obtained from the Daresbury Conference Office. I hope
to see you there.


                        A meeting organised by the 
        Collaborative Computational Project in Protein Crystallography (CCP4)
                and Daresbury Laboratory and sponsored by the 
                   EC Human Capital and Mobility Scheme

                           5th-6th January 1996
                             CHESTER COLLEGE

                         MACROMOLECULAR REFINEMENT

 The approach to the refinement of macromolecular models has changed radically 
 in the past few years. Structures are solved more quickly, and much less time
 is now devoted to understanding their details. This has partly arisen because
 more powerful algorithms such as those encoded in 'X-PLOR' make it apparently 
 easy to reach a satisfactory R-factor, and partly because the scientists are 
 often now primarily biochemists with little experience in the finer points 
 of the mathematical basis of refinement.

 This meeting will cover the underlying theory of different types of
 commonly used refinement, and explore new techniques.  There will be
 discussions on indicators which can detect both gross errors (which are
 rare) and sub-optimal refinement which is extremely common. Case studies
 will be presented which will underline the problems experienced in
 refining macromolecules.
 The invited speakers include:

     Paul Adams                (Yale)
     Gerard Bricogne           (LMB)
     Durward Cruikshank        (Manchester)
     Kevin Cowtan              (York)
     Randy Read                (Edmonton)                    
     Thomas Schneider          (Hamburg)                     
     George Sheldrick          (Goettingen)
     Lyn Ten Eyck              (San Diego)
     Dale Tronrud              (Eugene Oregon)
     David Watkin              (Oxford)

There is a registration fee of 45 pounds excluding accommodation. The fee 
provides for all meals during the meeting. Accommodation has been arranged at 
Chester College. Please note that the number of places is limited so early 
application is advisable.

                    HOW TO APPLY

Enquiries about the programme should be made to either Mrs. Eleanor Dodson
(Department of Chemistry, University of York, York Y01 5DD, Tel. +44/0 1904
432565, email: ccp4 at or Dr. Madeleine Moore (Department of 
Chemistry, University of York, York Y01 5DD, Tel: +44/0 1904 432584, 
email:moore at Additional application forms are available 
from the Conference Office, Daresbury Laboratory (Tel: +44/0 1925 603325 or 
Fax: +44/0 1925 603195, email: conference at

The closing date to attend the meeting is 5th November 1995. 


2. Sponsorship

Due to sponsorship from the EC Human Capital and Mobility scheme there is 
funding available to cover the travel, registration and accommodation costs of 
a number of young EC scientists. The term 'young' as defined by EC regulations 
is rather loose and people who have been living and working in the EC for over 
a year can also apply. Funding through CCP4 is also available to cover 
registration and one night's accommodation. Note that all sponsorship will only
be available to students and post-doctoral fellows/research assistants. Please
indicate on the application form if you wish to be considered, giving details 
of status, source of funding and for EC funding expected travel costs. Travel
should be by the cheapest form possible. Enquiries about this should be 
addressed to Dr. Adam Ralph, Daresbury Laboratory (+44/0 1925 603528, 
email: a.ralph at
