Evolution of missing data according to the threshold. For seven threshold values defining the maximal in-OTU/out-OTU distances ratio, the number of selected genes is plotted against the percentage of missing sites in the concatenated file. Subsets are extracted from the Metazoa dataset without making of chimera. The evolution of missing data is also displayed when the selection is only made according to the size criterion (black and grey curves respectively with and without making of chimera); these last selections represent the minimal amount of missing data for the dataset.
