      abstract     = {A reformulated implementation of single-sideband
                      ptychography enables analysis and display of live detector
                      data streams in 4D scanning transmission electron microscopy
                      (STEM) using the LiberTEM open-source platform. This is
                      combined with live first moment and further virtual STEM
                      detector analysis. Processing of both real experimental and
                      simulated data shows the characteristics of this method when
                      data are processed progressively, as opposed to the usual
                      offline processing of a complete data set. In particular,
                      the single-sideband method is compared with other techniques
                      such as the enhanced ptychographic engine in order to
                      ascertain its capability for structural imaging at increased
                      specimen thickness. Qualitatively interpretable live results
                      are obtained also if the sample is moved, or magnification
                      is changed during the analysis. This allows live
                      optimization of instrument as well as specimen parameters
                      during the analysis. The methodology is especially expected
                      to improve contrast- and dose-efficient in situ imaging of
                      weakly scattering specimens, where fast live feedback during
                      the experiment is required.},
