I am trying to use "tombo plot" commands to run plotting functions of ont-tombo 1.5.1 . I am getting a "rpy2 is not installed" error message , and I checked the singularity images "mopmod 0.5" and "mopmod 0.7" which don't seem to contain rpy2 files. Is it possible to create mopmod containers which contain the rpy2 and any other requirements for tombo plots?
