Dear Phenix, Whereas in previous version of Phenix (e.g. 1 year ago) I used to be able to run Real-space-refinement for cryoEM models using either a CCP4-map or coefficients from a MTZ file , in recent versions (e.g. currently using 1.19.1-4122-000) when I load an MTZ file, it puts data type File and this stalls upon running, but the data type cannot be changed. Is this a bug or a feature (to stop you using the MTZ file) or am I doing something wrong? thanks Stephen -- ********************************************************************** Dr. Stephen Cusack, FRS Head of EMBL Grenoble Group leader in the structural biology of protein-RNA complexes and viral proteins ********************************************************************** Email: [email protected], [email protected] Website: http://www.embl.fr Tel: (33) 4 76 20 7238 Secretary (33) 4 76 20 7123 Fax: (33) 4 76 20 7199 Postal address: EMBL Grenoble, 71 Avenue des Martyrs, CS 90181, 38042 Grenoble Cedex 9, France Delivery address: EMBL Grenoble, Polygone Scientifique, 71 Avenue des Martyrs, 38000 Grenoble, France **********************************************************************
