Dear colleagues,<div><br></div><div>We have some diffraction data from small peptide crystals, the shape of diffraction spots looks normal, and resolution is beyond 2A. The data were collected with 5 degree rotation per image. Later on we found it is hard to do index. Does anybody know some skills to figure this problem? </div>
