This event was a great success. The Organizing committee, Chaired by Eduardo Granado (Unicamp / LNLS) did a wonderful job. The sponsorship of several institutions and commercial firms (Lab. Nacional de Luz Síncrotron (LNLS), the IUCr, the Brazilian Crystallographic Assn (ABCr), the Research Foundations of the State of São Paulo (FAPESP) and of Minas Gerais (FAPEMIG), Centro Latino Americano de Física (CLAF), the International Center for Diffraction Data (ICDD), Bruker AXS, Rigaku Corp. and Panalytical) was critical to the success of both the Workshop and the Mini-Course and is very much appreciated. A touch of originality was provided by a soccer match organized the day of a visit to the synchrotron (NSLS) between the “locals” and the “visitors”. There is no agreement as to who were the winners of this match, but the crystallographic community has no doubts that they were all winners for attending this outstanding event.Iris Torriani and Eduardo Granado
