The table contains mean values and the corresponding standard deviations of Spearman's correlation coefficients calculated for 6 experiments. Correlations were computed between values of Welch's t-statistic calculated from MA and qRT-PCR measurements. Columns contain results for the 6 preprocessing algorithms, whereas rows contain results for the 6 filtering/mapping methods (negative signs are removed and values are multiplied by 100) after the new and the old annotations.
