The first thing you want to do when debugging hydrogens in refmac5 is to make sure it outputs whatever it was doing: MAKE HOUT Y This is not the default.  Normally, refmac will take a PDB file without any hydrogens in it, quietly add them before doing refinement, and then delete them before

Yes - I am having problems with hydrogens in REFMAC recently - has something changed? My problem is this: Build a rough model for some residues into a lousy map. (R ~ 32% etc..) I know it is rough with clashes and bad geometry but trust refinement to improve things a bit.. However if the run

Hi Fellows, for an experiment, I am running 0.9 A data with unrestrained Refmac (yes I know should/could use SHELXL, but let's drop that for now). When I select 'ignore even if present in file' in a PDB that has hydrogens, I get the identical results than with 'use if present' or 'generate
