+Although this example is delimited with spaces for consistent visualization, in a PCL file each element would be delimited by one tab.
+
+Here is an example of a very small PCL file.
+
+ID      Kingdom   Genus        Sample 1  Sample 2
+Cohort  NA        NA           Test      Control
+Age     NA        NA           34        43
+1232    Bacteria  Bacteroides  .23       .16
+543     Bacteria  Dorea        .001      .0021
+
