EdgeR: Filtering Counts Causes No Significance. When I filter my count data with the code in the user guide, the FDR for all my genes drops to 1.0. But, if I don't filter or set the CPM cut off to ~0.2, then I start to get significant DE genes. I'm a bit confused by this behavior.

WebMethods. This class inherits directly from class list, so DGEList objects can be manipulated as if they were ordinary lists. However they can also be treated as if they were matrices for the purposes of subsetting. The dimensions, row names and column names of a DGEList object are defined by those of counts, see dim.DGEList or dimnames.DGEList. WebThe documentation in the edgeR user's guide and elsewhere is written under the assumption that the counts are those of reads in an RNA-seq experiment (or, at least, a genomics experiment).If this is not the case, I can't confidently say whether your analysis is appropriate or not. For example, the counts might follow a distribution that is clearly not … cuban sandwich roswell rd
