create an OmicSignature object from differential expsignaturession matrix

updated 10/2024

Usage

OmicSigFromDifexp(difexp, metadata, criteria = NULL)

Arguments

difexp

Differential expression matrix

metadata

Metadata for the OmicSignature object. If `criteria` is `NULL`, the criterias to extract signatures will need to be provided in metadata. They can be specified in metadata fields as one or more of the followings: `logfc_cutoff`, `score_cutoff`, `adj_p_cutoff`, `p_value_cutoff`.

criteria

A character string to specify criterias used to extract signatures from difexp. e.g. "logfc > 5; score > 10". Alternatively, they can be provided in metadata fields: list("logfc_cutoff" = 5, "score_cutoff" = 10)

Value

OmicSignature object
