Graphically inspect a series of runs

While a refinement strategy for a series of runs is developed, it is useful to see quickly how refinements worked. While Cinema can do that, another way is to use the generated PNG files with a tool such as "Eye-of-GNOME" (eog) on Linux with a call like

eog run???/plot1d_Bank90*

to view e.g. all 1D plots for Bank 90 on HIPPO.
