PCT of collected phenotypes is the count of phenotypes collected by each category in a genus divided by the number of phenotypes expected to be collected in this genus. For example, in the category of Geography, each strain is expected to collect four phenotypes, including Continent, Country/Region, Geographic location, and Geographic coordinate. The number of Mycobacterium strains in the category of Geography is 107 and the count of phenotypes collected by these 107 strains is 194, thus PCT of phenotypes collected by Geography in Mycobacterium is 0.45 (194/4*107).
