Filter expression values based on a previously created quality matrix. Each expression value is filtered based on the corresponding quality value.
Defines the filter method that will be applied to the values in the expression columns (default: From quality matrix). If “From quality matrix” is selected, the filtering is just based on the previously created quality matrix (Create quality matrix) and a threshold must be specified (see parameter window A). If “Compare main to quality matrix” is chosen, the values of the two matrices are compared to each other in the way it is specified in “Values should be” (see parameter window B).
This parameter is just relevant, if the “Filter method ” is “From quality matrix”. It specifies which values of the matrix will be kept and which ones will be discarded (default: 0). Values lower than the defined “Threshold” will be filtered.
This parameter is just relevant, if the “Filter method ” is “Compare main to quality matrix”. It specifies how the values of the main matrix should be compared to the values of the quality matrix (default: Greater than). The operation how to compare the values of the two matrices can be chosen from a predefined list:
