The reason for the indexing failure in these cases seems to be the fact that the crystal changed its orientation within the SPOT_RANGE by more than ~ 0.1°. | The reason for the indexing failure in these cases seems to be the fact that the crystal changed its orientation within the SPOT_RANGE by more than ~ 0.1°. | ||
'''The other reason for this failure mode''' - but in this case there is only one SUBTREE with high POPULATION - is when the default <code>SEPMIN= 6.00 CLUSTER_RADIUS= 3</code> are used, but the spots are closer than 6 pixels. This often happens with Pilatus data; the recommendation for this detector is to use <code>SEPMIN= 4.00 CLUSTER_RADIUS= 2</code> in XDS.INP, or even <code>SEPMIN= 3.00 CLUSTER_RADIUS= 1</code>. | |||
