Hi all, I am still having issues with Autobuild giving errors during the combine step. I've downloaded the latest build and hope that will solve the problem, but in the mean time I'm having an issue trying to combine the models. I've been following the script: #!/bin/csh -f #COMBINE_MODELS SCRIPT if (-d PDS || -d AutoBuild_run_1_) then echo "Please run in a directory without PDS or AutoBuild_run_1_" exit 1 endif echo "Setting up combine models with a dummy run. NOTE: multiple_models_group_number must be correct" phenix.autobuild fobs.mtz multiple_models=true seq_file=seq.dat combine_only=true multiple_models_group_number=2 multiple_models_number=1 > dummy_autobuild.log echo "Copying files to AutoBuild_run_1_/MULTIPLE_MODELS" mkdir AutoBuild_run_1_/MULTIPLE_MODELS cp coords1.pdb AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.pdb_1_1 cp coords2.pdb AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.pdb_1_2 cp map_coeffs_1.mtz AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.mtz_1_1 cp map_coeffs_2.mtz AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.mtz_1_2 ls AutoBuild_run_1_/MULTIPLE_MODELS/ echo "Running autobuild to combine files in AutoBuild_run_1_/MULTIPLE_MODELS" phenix.autobuild combine_only=true seq_file=seq.dat carry_on=true run=1 > autobuild_combine.log # END OF COMBINE_MODELS SCRIPT # Here are the two log files. I used the expl_fobs_phases_freeR_flags.mtz as fobs.mtz and changed each overall_best.pdb and overall_best_refine_map_coeffs.mtz as the model and map to combine. Thanks, Heather
