Abstract / Description:Single−particle experiments using X−ray Free Electron Lasers
produce more than 105 snapshots per hour, consisting of an admixture of
blank shots (no particle intercepted), and exposures of one or more particles.
Experimental data sets also often contain unintentional contamination with
different species. We present an unsupervised method able to sort
experimental snapshots without recourse to templates, specific noise
models, or user−directed learning. The results show 90% agreement with
manual classification
