Methods and systems for imaging interactions between particles and fragments are provided. A method includes applying a template to one or more images of a sample comprising a particle and a fragment. The template comprises a three-dimensional representation of the particle at a resolution of higher than about ⅛ reciprocal Angstroms and is produced by data independent of data provided in the one or more images. The fragment is not represented in the template. A similarity image is produced comprising a pixel-wise representation of a distance metric between the template and the one or more images. The distance metric enables detection of at least a portion of the particle or fragment. A threshold is applied to the similarity image to distinguish positive detections from noise and a representation of a volume as a function of the positive detections is produced, representing an interaction between the particle and the fragment.
