SIG-09 Crystallographic Computing


SIG 9 Workshops

SIG9 (also called ECACOMSIG) is organising a two full day Computing Workshop at Hotel Sonnenrain in Loßburg-Wittendorf, near Freudenstadt, in the Black Forest, Germany. It will be associated with the European Crystallographic Meeting (ECM30) which is in Basel, Switzerland.

The Workshop begins on the afternoon of 25th August and finishes at lunchtime on 28th August. Transport will be provided to Basel, and will arrive in time for the ECM30 opening ceremony. Registration is via the SIG9 Website at

Scope and Objectives

ECACOMSIG (or “SIG9”) is the ECA’s Special Interest Group that promotes all aspects of Computing in Crystallography. As such, its activities are central to most of the other SIGs in the ECA.

ECACOMSIG works closely with the International Union of Crystallography’s Commission on Crystallographic Computing (“CompComm”) to organise Microsymposia at meetings of the ECA and the IUCr and to organise Schools for developers and potential developers in computational methods for Crystallography.

Martin Lutz, Crystal and Structural Chemistry, Bijvoet Center for Biomolecular Research, Faculty of Science, Utrecht University, Padualaan 8, 3584 CH Utrecht, The Netherlands
