Hi, When I run phenix.autosol with this scripts (phenix.autosol data=output-anomalous.sca input_phase_file=AutoMR_run_10_/MR.1.mtz input_phase_labels="F PHIC FOM" f_prime=-8.13 f_double_prime=5.61 kp-zntb.seq atom_type=Zn), the job is terminated by the error message. Does anyone know what I should do? I am using Phenix-1.5 version. Floating-point error (Python and libc call stacks above) This crash may be due to a problem in any imported Python module, including modules which are not part of the cctbx project. To disable the traps leading to this message, define these environment variables (e.g. assign the value 1): BOOST_ADAPTBX_FPE_DEFAULT BOOST_ADAPTBX_SIGNALS_DEFAULT This will NOT solve the problem, just mask it, but may allow you to proceed in case it is not critical.
