In these four cases, the percentage of finding correct or partially correct solutions in SHELXD runs using the SIRAS method was much higher than in the corresponding runs using the SAD method, by as much as 60-fold. However, the corresponding PHENIX AutoSol runs failed to find any correct solutions using either the SIRAS or SAD methods.
