[求助] 请问，怎么从GEO数据库得到一些基因在不同组织的表达谱数据？

我要做20个基因的heatmap，需要这些基因的表达谱数据，比如这是一篇文章的图表及附注，里面提到用NCBI上的Gene Expression Omnibus （GEO）数据库，具体怎么找，麻烦大家帮帮忙

Figure 2. Hierarchical clustering of transcripts for genes encodingMCproteins from rice. The Affymetrix rice genome microarray
data were derived from the Gene Expression Omnibus within the National Center of Biotechnology Information database. The
normalized data were hierarchically clustered using average linkage based on Euclidean distance. Genes annotated with carets
indicate that these genes were absent in dry seeds, during early germination, and in more than four other tissues/stresses. A, Air;
N, nitrogen.
