== Abstract ==

The interpretation of cryo-EM maps often includes the docking of known or
predicted structures of the components, which is particularly useful when the
map resolution is worse than 4 A ˚ . Although it can be effective to search the
entire map to find the best placement of a component, the process can be
slow when the maps are large. However, frequently there is a well-founded
hypothesis about where particular components are located. In such cases, a local
search using a map subvolume will be much faster because the search volume
is smaller, and more sensitive because optimizing the search volume for the
rotation-search step enhances the signal to noise. A Fourier-space likelihoodbased
local search approach, based on the previously published em_placement
software, has been implemented in the new emplace_local program. Tests
confirm that the local search approach enhances the speed and sensitivity of the
computations. An interactive graphical interface in the ChimeraX moleculargraphics
program provides a convenient way to set up and evaluate docking
calculations, particularly in defining the part of the map into which the
components should be placed.
