tsea.analysis {deTS}

Tissue-specific enrichment analysis for query gene list

Description

Tissue-specific enrichment analysis by Fisher's Exact Test for given gene list.

Usage

tsea.analysis(query_gene_list, score, ratio = 0.05,
p.adjust.method = "BH")

Arguments

query_gene_list

a gene symbol list object.

score

a gene tissue-specific score matrix, c("GTEx_t_score" or "ENCODE_z_score"), can be loaded by data(GTEx) or data(ENCODE), the default value is recommended "GTEx_t_score".

ratio

the threshold to define tissue-specific genes (with top t-score or z-score), the default value is 0.05.

p.adjust.method

p.adjust.method, c("holm", "hochberg", "hommel", "bonferroni", "BH", "BY", "fdr", "none")

Details

Tissue-specific enrichment analysis by Fisher's Exact Test for given gene list.

Value

A data frame with p-value of tissue-specific enrichment result.

Rows stand for tissue names and columns stand for sample names.

Note

nothing
