Ways of solving the phase problem in electron diffraction will be discussed including: extraction of structure factor phases from high resolution election micrographs; direct methods applied to electron diffraction intensity data; phase invariants from dynamical effects in convergent-beam electron diffraction (CBED); coherent CBED. Application to structure determination will be dealt with as well as the problems and possibilities associated with dynamical diffraction.

Cambridge Structural Database (CSD)

4th August 1999, SECC, Glasgow, Scotland

This workshop demonstration will cover the CSD System, including a preview of new search and visualisation software, and will also cover knowledge bases derived from the CSD (e.g. IsoStar), and related applications software. The demonstration is designed to make participants aware of all recent developments in the CCDC's information services, and to provide a preview of future plans. This half-day workshop is limited to around 150 participants.

Structure Determination from Powder Diffraction Data

4th August 1999, SECC, Glasgow, Scotland

he aim of this workshop is to give an overview of the state of the art of structure determination (and refinement) from powder diffraction data by some of the world's leading experts in this field. The ab initio determination of structures from powder diffraction data is a brand new but rapidly growing field which has seen exciting progress during the past few years. Besides the adaptation and improvement of traditional structure solving tools, many new methods have been developed, some of which will be presented here in detail. The workshop will concentrate on the practical aspects of structure determination from powder data and will show the possibilities as well as the limitations of the different methods.

Simulating crystals as a teaching tool and to analyse defect structures

11th August 1999, Strathclyde University, Glasgow, Scotland

Simulating crystals in the computer is a very efficient tool to teach crystallography and diffraction physics. All aspects of a structure and the diffraction prozess can be simulated free from physical constrains. This allows a thorough teaching with intensive student involvement. We will demonstrate the use of computer simulations in a wide field of structural aspects.
The second part of the workshop will deal with the simulation of crystal structures containing defects as a tool to interprete diffuse scattering experiments. We will show simulation techniques of complex defect structures and modern analysing techniques.

CCP4 introductory workshop

4th August 1999, 10 a.m. - 4 p.m. Alsh Lecture Theatre, SECC, Glasgow, Scotland

CCP4 are holding a 1-day informal introductory course to the CCP4 suite of programs for protein crystallography on the opening day of the IUCr congress, 4th August. The programme is not yet finalised, but will consist of introductory talks (provisional speakers: Kevin Cowtan, Eleanor Dodson, Phil Evans, Garib Murshudov, Martyn Winn), as well as more detailed discussions and/or problem solving in small groups. More details will be posted here as they become known. The course is aimed at students and those relatively new to the CCP4 suite, and will be similar in spirit to that held at the beginning of last year's ECM conference in Prague.

Lunch will be provided, but delegates must make their own travel and accomodation arrangements (via registration for the main IUCr conference). To register for this workshop, please fill out the registration form. No acknowledgement will be sent, but a list of registrations received is available here. Numbers will be limited to 100 - in the case of there being more applicants, we will try to select those who will gain most and also try to achieve an even spread over institutions. In case of queries, please email ccp4conf@dl.ac.uk.
