Run === The following steps show roughly how to refine models (either top models from global fitting or locally optimize rigid bodies in general). #. I you haven't yet, activate your modelling virtual environment before using the Assembline software by .. code-block:: bash source activate Assembline or depending on your computer setup: .. code-block:: bash conda activate Assembline #. Enter the main project directory (e.g. ``IR_asymmetric_unit_refinement``) and create ``params.py`` and ``config.json`` files according to Assembline manual. While in the main project directory run the following .. code-block:: bash assembline.py --traj --models -o out --multi --start_idx 0 --njobs 500 config.json params.py .. note:: In order to set up and run refinement for multiple models then instruct the `Elongator manual `__ and `Assembline manual `__.
