Individual scaled unmerged data is stored in <code>*unmerged.mtz</code>. However, full deposition-ready PDBx/mmCIF files are already generated (including multiple datablocks with merged and unmerged data) - including the full set of data quality metrics: <code>Data_1_autoPROC_STARANISO_all.cif</code> (for the anisotropic/STARANISO analysed data) and <code>Data_2_autoPROC_TRUNCATE_all.cif</code> (for the traditional/isotropic data). These can be used as-is for deposition and no subsequent format conversion from MTZ is required. Furthermore, no additional extraction of data quality metrics should be necessary. If [https://www.globalphasing.com/buster/ BUSTER] was used for structure refinement, the <code>aB_deposition_combine</code> tool can be used to combine the reflection mmCIF file from refinement with this one from data processing - and transfer the correct set of data quality metrics into the model mmCIF file. | |||
