h1. Run Feature Analysis

Feature analysis refers to systematic techniques for extracting features from a series of [[Run_Alignment| aligned particles]] with the intent of clustering images with with similar features together. Feature anaylsis is closely related to multivariate statistics . All of these feature analysis techniques fall into two categories: principal component analysis (PCA) (Spider Coran and IMAGIC MSA) and neural networks  (Xmipp KerDen SOM).
