For example, one can imagine using Python to carry out some transformations on flow cytometry data, but then use other flow cytometry tools to visualize and further process the data. Since all these tools accept read FCS files, it would be nice to be able to save Python-transformed data in FCS format.
I don't have the capacity to that myself (not working with flow cytometry data anymore) -- but I'd be happy to accept PR here, if you're willing to spend the time!
