rsref is a scripted modular workflow for the refinement of atomic models against high-resolution cryo-EM density maps. It also features graphical output for model validation. It is a not a standalone refinement software, but rather provides a set of tools for model and/or map manipulation, refinement protocols, the analysis of the refinement cycles and validation of the resulting coordinate models.
Atomic coordinate refinement is not a trivial task at low resolution (3.5 - 6.0 A). The scripts and programs provided here are intended to help make decisions and automate the process, in particular for maps with a substantial degree of resolution variation.
If rsref is useful for your research please acknowledge its use.
