AbstractMacromolecular models building from cryo-electron microscopy (EM) density maps requires fitting strategies to localize available atomic structures. To this end, we developed several approaches that are efficient enough to run as command line tools on commodity hardware. For rigid-body fitting, ADP_EM employed spherical harmonics to speed up the rotational part of the exhaustive search whereas for flexible fitting, iMODFIT exploits Normal Model Analysis to reduce the explored conformational space. Here, we present the update and integration of such tools into UCSF Chimera to enable interactive macromolecular fitting into the facto standard visualization tool of the EM community.
