[phenixbb] Xtriage systematic results is not consistent with HKL2000

Dear All, I scaled a dataset of SG P2221 in HKL2000 and got systematic absence results as below, it seems clearly HKL2000 showed the data had systematic absence violations, but when I used the .sca file from HKL2000 as input in Xtriage, the result did not show any systematic violations. Which result should I rely on?

For each space group, the number of systematic absence violations are listed under the '+++' column. The number of non-absence violations (weak reflections) are listed under '---'. The last column is a likelihood based score for the particular space group. Note that enantiomorphic spacegroups will have equal scores. Also, if absences were removed while processing the data, they will be regarded as missing information, rather then as enforcing that absence in the space group choices. ------------------------------------------------------------------------------------- | space group | # absent | <Z>_absent | _absent | +++ | --- | score | ------------------------------------------------------------------------------------- | P 2 2 2 | 0 | 0.00 | 0.00 | 0 | 4 | 0.000e+00 | | P 2 2 21 | 0 | 0.00 | 0.00 | 0 | 4 | 0.000e+00 | | P 2 21 2 | 5 | 3.07 | 16.77 | 5 | 4 | 1.038e+01 | | P 2 21 21 | 5 | 3.07 | 16.77 | 5 | 4 | 1.038e+01 | | P 21 2 2 | 5 | 1.89 | 15.21 | 5 | 4 | 1.250e+01 | | P 21 2 21 | 5 | 1.89 | 15.21 | 5 | 4 | 1.250e+01 | | P 21 21 2 | 10 | 2.48 | 15.99 | 10 | 4 | 2.288e+01 | | P 21 21 21 | 10 | 2.48 | 15.99 | 10 | 4 | 2.288e+01 | ------------------------------------------------------------------------------------- ----------List of individual systematic absences---------- Note: this analysis uses the original input data rather than the filtered data used for twinning detection; therefore, the results shown here may include more reflections than shown above.
