Table 3. SAD phasing results for OmpK36 (top) and Cld (bottom): statistics from Crank2 for all four absorption correction strategies.
While for some strategies only two data sets were needed for successful phasing, the statistics from using three data sets are presented for comparison.
| Strategy | No. of data sets required for phasing | Completeness (overall/high-resolution bin) | Multiplicity (overall/high-resolution bin) | Refinement R factor/R free | No. of correct residues automatically built/total No. of residues |
