Arabidopsis embryo dataset contains gene expression levels (3625 genes and 7 embryo samples) from Xiang et al. (2011). This dataset has been pre-processed: capping into floor of intensity 777.6; 2-base logarithmic transformation; row/gene centering; and keeping genes with at least 2-fold changes (in any stage) as compared to the average over embryo stages.

Xiang: a gene expression matrix of 3625 genes x 7 stage
samples. These embryo stages are: zygote, quadrant, globular, heart,
torpedo, bent, and mature.
