After opening a Gaussian log file (or corresponding gjf file) in GaussView, the log file can be displayed statically or dynamically in a searchable, highly customizable GaussView window called a File Stream Viewer. A File Stream Viewer can be launched via the "Results" menu or via the "Current Jobs" dialog or via a button in the lower left of a view window associated with a "Gaussian Quick Launch" job.
Right-clicking in a File Stream Viewer window will popup a menu with a variety of useful features.
