ECACOMSIG - the European Crystallographic Association's Computing Special Interest Group

ECACOMSIG organises training workshops in Crystallographic Computing before European Crystallographic Meetings (ECMs), which take place every year in which there is not an IUCr General Assembly and Congress. It also organises plenary and keynote lectures and several microsymposia ("MS") at the European Crystallographic Meeting.

Martin Lutz organises a Software Fayre at the ECM, which showcases a wide variety of Crystallographic software.
