The main piece of information in every ddPCR plate is the droplets data,
which contains the fluorescence intensities for every single droplet in
every well. After a ddPCR plate gets analyzed, this data also includes the
assigned cluster for each droplet. The plate data may be useful programatically,
but it's not very useful to a human, so if you want to visualize the plate data
you should instead plot it using plot.ddpcr_plate
.
