COLSPOT: is the "number of spots" evenly distributed among the frames? If not, it may be a sign of radiation damage or anisotropy, or plate-shaped crystal.

IDXREF: are the "CLUSTER INDICES" of the difference vectors integer numbers, or close to integers? Are the cell parameters reasonable? Is the first POPULATION of the first SUBTREE close to 3000? See [[IDXREF.LP]] and [[IDXREF]] . | IDXREF: are the "CLUSTER INDICES" of the difference vectors integer numbers, or close to integers? Are the cell parameters reasonable?

INTEGRATE: are the curves smooth (good) or are there jumps (bad)? Try to think of reasons! Could it be the beamline flux or the crystal changing? Are their straight red and green lines in the "Beam divergence" and "Mosaicity" plots? If not, few strongs reflections were found and you should add DELPHI=20 in XDS.INP, or increase the value if the line already exists. | |||
