Computational determination of a proteins 3D atomic structure remains largely an open question in bioinformatics. Electron cryo-microscopy (CryoEM) produces 3D images density mapsof molecules, but they must be interpreted to derive the underlying atomic structures. We seek to measure the lengths of segments of protein polymer chains associated with specific regions of the density map. We briefly discuss past efforts, and introduce an analog to robot motion planning as a novel approach. We will show this new approachs superiority through complexity analysis, and present some experimental results in the 2D case, leaving the 3D case to future work.
