Dear all, I have two requests: 1) I have trouble getting a molecular replacement job to run (Phenix Version 1.7.3-928), where I want to keep one ensemble fixed in its known orientation, only looking for a second ensemble. I keep on getting the following error message, both from the GUI and from command line (using a 'mymr.eff' parameter file): **************************************** AutoMR Input failed Python argument types in SOLU.addSOLU_6DIM_ENSE(InputMR_AUTO, str, list, bool, list, float, bool, bool, bool) did not match C++ signature: addSOLU_6DIM_ENSE(phaser::SOLU {lvalue}, std::string, scitbx::vec3<double>, bool, scitbx::vec3<double>, double, bool, bool, bool, bool, scitbx::vec3<double>, double) **************************************** *************ERROR ENDING ******************* I can't figure out what I'm doing wrong. Any suggestions? 2) Which parameters would I need to specify to let phenix.autobuild build a model for one protein of a 2-component complex from scratch, while keeping the other component unchanged (and using it to calculate the phases)? Is that possible? Thanks for help, best regards, Maike --
