It turns out that the spot shapes are actually so irregular that XDS stops after the IDXREF step, with a long warning message. This is because it cannot index (within default error margins) enough reflections (50% is the cutoff). When that occurs, one simply continues with the step after IDXREF: | It turns out that the spot shapes are actually so irregular that XDS stops after the IDXREF step, with a long warning message.

Other than that, the three MAD wavelengths can be processed once with default parameters, as written into [[XDS.INP]] by [[generate_XDS.INP]]. This data reduction therefore proceeds in spacegroup P1, but the correct spacegroup (22) is identified by CORRECT. | Other than that, the three MAD wavelengths can be processed once with default parameters, as written into [[XDS.INP]] by [[generate_XDS.INP]].

Afterwards, another xds_par run gives the final intensities. Repeating this optimization sometimes helps. | Afterwards, another xds_par run gives the final intensities. Repeating this optimization sometimes helps. | ||
