Option 1:
No filtering
Option 2:
Filter by Sum
(Analytes whose sum for all samples falls below the threshold % will be excluded)
Option 3:
Filter by Mean
(Analytes whose mean for all samples falls below the threshold % will be excluded)
Option 4:
Filter by Median
(Analytes whose median for all samples falls below the threshold % will be excluded)
Option 5:
Filter by Sample threshold
At least one of the 2 selected groups
Both groups
must exceed the above threshold per analyte
In order for an analyte to be retained, the % of samples in one/both groups which are non-zero must exceed the threshold.
Option 6:
Remove all analytes containing null values
