Goal

Accuracy as a function of isotope incorporation & gradient fraction size

acc ~ fraction_size + incorp

Variable parameters:

  • atom % isotope incorporation
    • 0, 15, 25, 50, 75, 100
  • gradient fraction size
    • 0.003, 0.004, 0.006, 0.008
  • n-reps (stocastic: taxon abundances & which incorporate)
    • 10
