P-values were calculated for each of 3072 genes, for data that compared expression values between post-settlement coral larvae and pre-settlement coral larvae.
The format is: num [1:3072, 1] 8.60e-01 3.35e-08 3.96e-01 2.79e-01 6.36e-01 ...
t-statistics, and hence p-values, were derived from five replicate two-colour micro-array slides. Details are in a vignette that accompanies the DAAGbio package.

## From p-values, calculate Benjamini-Hochberg false discrimination rates fdr <- p.adjust(DAAG::coralPval, method='BH') ## Number of genes identified as differentially expressed for FDR = 0.01 sum(fdr<=0.01)
