Defines the minimal number of valid values each row needs to have in the expression columns to survive the filtering process (default: 3).

Defines, which expression columns are counted to define, if a row has enough valid values to survive the filtering process (default: In total). There are three options available:

• In total (includes all expression columns)
• In each group
• In at least one group

This parameter is just relevant, if “Mode” is set to “In each group” or “In at least one group”. It defines the grouping of the expression columns that should be used by selecting a categorical row (default: first categorical row of the matrix).

Defines the restriction for a value to be classified as valid (default: Valid). There are seven different possibilities to specify, which entry is counted as a valid value (default: Valid):

1. Valid
2. Greater than
3. Greater or equal
4. Less than
5. Less or equal
6. Between
7. Outside

The “Filter mode” defines, whether the input matrix will be reduced (“Reduce matrix” = default) or a new categorical column called “Filter” will be generated containing the categories “Keep” and “Discard” (“Filter mode” = “Add categorical column”).
