Tomogram reconstruction and template matching against a single particle cryo-EM reconstruction of the 73S yeast mitoribosome were accomplished using PyTom. Tomogram areas corresponding to cross correlation peaks within mitochondria were visually inspected to identify true positive matches. For the retained coordinates, unbinned subtomograms were reconstructed individually from the weighted projections and iteratively aligned using PyTom. Aligned subtomograms were classified using constrained principal component analysis.
