Because my mathematics background is very weak, maybe it is difficult for me to understand on those functions describing the strain. Thanks everyone, and I will try my best to catch it. Thanks all again! Happy new year! Best regards, Daxu

Hi, everyone, Someone can supply some information on analyzing strain using GSAS? Because one of the reviewers asked me to determine the stain of biogenic calcite, however I don't know how to analyze the refinement data to obtain the strain. I wonder whether the resolution of conventional Bragg-Brentano X-ray diffratometer is able to determine the strain. I know GSAS does describe the strain using some functions for conventional XRPD data. How to output the corresponding data to calculate the strain. Best regrads, Daxu
