Hi Luca, You should find that the hydrogens in the mmCIF file output by Refmac are flagged as riding hydrogens, not as an explicit part of the model. This behaviour is as intended, and should not pose a problem for deposition. They are not in the output PDB file because there is no way to flag

Hi, just to clarify one point on the GUI. You can click or unclick the option "use hydrogens during refinement" on the first tab in i2 GUI in the options field. As indicated it used it only during refinement and does not put it into the output pdb. In the output tab you can choose what should

Hello, just to clarify, I do not use H atoms for refinement, but as idealised riding H atoms. In the old-style GI of Refmac one could use riding hydrogens during refinement without adding them in the output coordinate file. I do not find this option in the new GI of the CCP4i2 window. As a

Dear CCP4 people, Refining a 1.7 Angstroem structure with REFMAC (CCP4i2) using hydrogens during refinements by generating riding hydrogens I obtain a PDB file that does not contain H atoms. However, the corresponding mmcif file that I should use for deposition contains their coordinates and
