< p > One of the most important features of this package is the complete microbial taxonomic database, supplied by the Catalogue of Life (< a href = "http://catalogueoflife.org" class = "uri" > http://catalogueoflife.org< / a > ). We created a function < code > < a href = "../reference/as.mo.html" > as.mo()< / a > < / code > that transforms any user input value to a valid microbial ID by using AI (Artificial Intelligence) combined with the taxonomic tree of Catalogue of Life.< / p >
< p > Using the < code > microbenchmark< / code > package, we can review the calculation performance of this function. Its function < code > < a href = "https://www.rdocumentation.org/packages/microbenchmark/topics/microbenchmark" > microbenchmark()< / a > < / code > runs different input expressions independently of each other and measures their time-to-result.< / p >

< p > In the table above, all measurements are shown in milliseconds (thousands of seconds). A value of 10 milliseconds means it can determine 100 input values per second. It case of 50 milliseconds, this is only 20 input values per second. The more an input value resembles a full name, the faster the result will be found. In case of < code > < a href = "../reference/as.mo.html" > as.mo("B_STPHY_AUR")< / a > < / code > , the input is already a valid MO code, so it only almost takes no time at all (404 millionths of seconds).< / p >
< p > To achieve this speed, the < code > as.mo< / code > function also takes into account the prevalence of human pathogenic microorganisms. The downside is of course that less prevalent microorganisms will be determined far less faster. See this example for the ID of < em > Mycoplasma leonicaptivi< / em > (< code > B_MYCPL_LEO< / code > ), a bug probably never found before in humans:< / p >
