About fit libraries
===================

Fit libraries are lists of possible positions of your input structures in the EM map.
The positions are used in the *global optimization* step to generate a large number of combinations of the fits
through a Monte Carlo integrative modeling procedure. Each position has its associated score and p-value,
which are used as EM restraints during the modeling.

Read more about fit libraries in the `manual <https://assembline.readthedocs.io/en/latest/fit_libraries_intro.html>`_.

The fit libraries are typically generated by fitting every input structure into the EM map separately.
For this tutorial, the fit libraries are already provided in the ``fits/`` directory.

Follow the next steps if you want to generate them yourself using Efitter package,
which is a wrapper around `UCSF Chimera FitMapTool <https://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/midas/fitmap.html>`_ .
