Tabulation of sequence abundance/prevalence. The Summary Table dialog provides multiple means of tabulating sequence data. In this example, rows are defined by the values of a meta-data key (e.g. 97% OTUs), while columns are defined by the value associated with another meta-data key (e.g. PCR results). The "Data Format" panel specifies that sequence counts in each column are normalized to the total of each column.
