Is anyone having issues executing ensemble refinement in Phenix? I've tried several times now to run things and it always crashes without returning any maps and just returning a set of large PDB files such as: "TEAS-W273E-FPP-A_ensemble_0.6.pdb, TEAS-W273E-FPP-A_ensemble_0.8.pdb, TEAS-W273E-FPP-A_ensemble_0.9.pdb and TEAS-W273E-FPP-A_ensemble_0.1.pdb". The log file always ends with: " Time building chain proxies: 3.01, per 1000 atoms: 0.35 Number of scatterers: 8638 At special positions: 0 Unit cell: (125.75, 125.75, 120.07, 90, 90, 90) Space group: P 41 21 2 (No. 92) Number of sites at special positions: 0 Number of scattering types: 7 Type Number sf(0) S 19 16.00 P 2 15.00 Mg2+ 3 10.00 O 835 8.00 N 717 7.00 C 2765 6.00 H 4297 1.00 sf(0) = scattering factor at diffraction angle 0. AttributeError" I only entering a single chain with solvent and ions and hydrogens. All of the other parameters from the GUI are kept the same. Any suggestions or comments would be much appreciated.
