I'm struggling to work with some published example data that has a companion gatingML file. I want to begin by viewing and plotting all the gates in the analysis schema, ideally with some illustration of the hierarchies.

It's the Nilsson_rare dataset from this flowrepository?

Suggestions for a good reference or example?

Use CytoML to Import gatingML generated from Cytobank. See https://github.com/RGLab/CytoML Then visualize the gates by ggcyto
