Rarefaction curve from Roary output

I have carried out the pangenome analysis of some 98 genomes, and obtained the outputs. But I am unable to find a way to derive a rarefaction curve from the obtained outputs.

Does anyone know any methodology?

Hi @Jennifer_Nester,
I updated the tool in order to include the rarefaction curve plots Roary: include parameters by gallardoalba · Pull Request #4518 · galaxyproject/tools-iuc · GitHub. Probably it will be available in a few days.
