A list with two data frames and one list.
geneexp
expression levels of of 722 genes.
snps
genotypic values of 732 SNPs.
ciseqtl
a list of the indices of cis-eQTL for each gene.
The experiment included 112 segregants from a cross between two strains BY4716 and RM11-la (Brem and Kruglyak, 2005). The data here only keep 722 genes which have marginally significant cis-eQTL (p-value < 0.05). The set of cis-eQTL for each gene was filtered to control a pairwise correlation under 0.90, and then further filtered to keep up to three cis-eQTL which have the strongest association with the corresponding gene expression.
