Impact of analysis parameters on the numbers of taxonomic units obtained for a bulk-bone sample.

<p>A number of analysis parameters were used to analyse a complex mixture containing numerous taxa. Different quality and abundance filtering methods were used in addition to two taxonomy-independent measures of analysis, full definitions and explanations of which are in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0124671#pone.0124671.g001" target="_blank">Fig 1</a>. The spread in the numbers of taxonomic units obtained across the combinations of parameters chosen is seen. The radius of each semicircle represents the number of taxonomic units obtained given a set combination of the parameters used. The number of taxonomic units is also indicated above each semicircle. Each semicircle is proportional to all others. AFM—abundance filtering method; QFM—quality filtering method; TIM—taxonomy-independent method.
