Table 1

Absolute and relative (in parentheses) concordances between different normalization algorithms applied to MAS5 expression values. The numbers of genes declared DE are determined using the local false discovery rate [8] at 0.1% limit. Percentages in parenthesis are relative to the method in the column headings. The last line reports the percentages of over-expressed genes among those declared DE.
