Couldn't the lines be explained most simply by extreme mosaicity, perhaps severely anisotropic? If not, why not? What were the values obtained in integration?

  Subject: [ccp4bb] small lines in diffraction pattern


  Dear all,


  In the diffraction pattern of crystals of an RNA decamer, small lines appeared (see pictures attached). We've tried different crystals but they all showed the same small lines. �Has anybody seen this�phenomena�before and has got an explanation for it please..?


  Many thanks
