The density.grid_search() function outputs a 'bestCC_targ' file which
contains the CCF. Is there a way to use this information for model
building? A web tutorial or Python code on how to use electron
microscope density maps for model building would be helpful.
grid_search is for static fitting of models into density maps, e.g. for
model assessment. It is not suitable for guiding the model building
procedure itself. You could, however, check out Flex-EM at
http://salilab.org/Flex-EM/ and check out the referenced paper to see if
that is helpful for you.
