Dear, My name is Alessandro Lisboa. I am a phd student of physics in Brazil - University of Brasilia. In the last February was held the first experiment DAFS in the Laboratório Nacional de Luz Síncrotron of Brazil. I performed this experiment and now I'm trying to analyze the data. I am having difficulty to establishing a procedure for analysis. I've read many things about. I tried to generate the diffkk.inp but I can not get result. I do not know what I'm doing wrong. I ask, please, help me with a procedure to analyze. For example, what is the sequence of files that need to create and run? I would be eternally grateful for your help.
