I found the PDB entry name in many fields: _atom_sites.entry_id '5HVP' _cell.entry_id '5HVP' _cell_measurement.entry_id '5HVP' _computing.entry_id '5HVP' _database.code_PDB 5HVP _database_2.database_code 5HVP _diffrn.entry_id '5HVP' _diffrn_measurement.entry_id '5HVP' _diffrn_radiation.entry_id '5HVP' _entry.id 5HVP _phasing_isomorphous.parent 'PDB entry 5HVP' _refine.entry_id '5HVP' _reflns.entry_id '5HVP' _struct.entry_id '5HVP' _symmetry.entry_id '5HVP' 1. Why is the entry name not in quotes for some while it is in quotes for the others? 2. Shouldn't the data for _phasing_isomorphous.parent be '5HVP' rather than 'PDB entry 5HVP'? Frances C. Bernstein
