I recently generated a cladogram on GraPhlAn from my Metaphlan2 output and wanted to add a ring displaying the relative abundances of each clade. I created a text file with this information according to the example (https://bitbucket.org/nsegata/graphlan/src/default/examples/guide/annot_3.txt). The issue is that my dataset (the 20 most abundant clades) is mainly dominated by one clade (83%, and the next most abundant is at 11% then 3% all the way down to 0.00173%) and therefore the image looks ridiculous (one giant bar from one place and the rest are basically invisible). My question is; what's the best way I can normalize these numbers so I get a reasonable range that would display the true abundances of the clades on the figure? any ideas?
