Coexpressed gene search

Coexpressed gene rank

In COXPRESdb co-expressed gene search, correlation rank is used rather than correlation value itself. Rab indicates correlation rank from gene A to gene B.

Example: Top 5 co-expressed gene list for gene A

Rank Cor Locus
0 1.00 gene A
1 0.93 gene E
2 0.93 gene D
3 0.93 gene B
4 0.93 gene C
5 0.92 gene F

In this case, Rab = 3.

We do not introduce any cut-off threshold. Namely even if the correlation value between two loci is insignificantly low, the ranks are numbered from the strongest pair to the weakest pair.

Search from multi gene query

For each gene A of 21036 genes that have gene expression data in COXPRESdb, average rank Rqa to query genes is calculated.

, where q is a set of query genes, Nq is the number of genes in set q.

Genes are sorted according to the Rqi value (i ∈ 21036 genes).
