doBISEPAnalysis: BISEP Analysis

Description Usage Arguments Value

Description

The BISEP analysis function identifies genes with bimodel expression profiles. See BiSEp documentation. Note that the version of BISEP used is slightly modified and not that from the BiSEp package - see BISEP_cv for more details.

doBISEPAnalysis(con, genes_n = 1e+05, table_name = "tcga_rnaseq_data",
  log2_transform = TRUE, gene_var_th = 0.2, gene_naprop_th = 0.3,
  seed_val = NULL)

Arguments

con

A SQLiteConnection object

genes_n

Permits a random subsample of genes to be analysed rather than the full set. Default 100000 - ie all.

table_name

The table in the SQLite database containing the data. The table should have fields named patient_id, gene_id and value where gene_id is an ensembl id. Default tcga_rnaseq_data

log2_transform

Boolean operator to determine whether data should be log2 transformed. Default TRUE

gene_var_th

Genes with very low variance can cause BISEP to fail. Increasing the gene variance threshold parameter can filter out these genes. Default 0.2

gene_naprop_th

Genes with a higih proportion of NA values can cause BISEP to fail. Decreasing the proportion of NA's filter can filter out these genes. Default 0.3.

seed_val

Setting this parameter ensures that consistent BISEP p-values are returned from run to run but there is no parallelisation so the analysis will take longer. See set.seed for more details. Default is NULL - no seed set.

Value

A data frame
