For each model listed, the number of experiments (#exp), the number of biological conditions (#biol), and the number of samples (#points) are indicated. Columns labelled "before filtration" indicate the raw figures at the time the data were downloaded. Columns labelled "first filtration", "end filtration", and "NR filtration" indicate the figures obtained once the unusable (first and end) and redundant samples (NR) were eliminated. For these three groups, the number of samples is twice the number of biological conditions.
