gene_expression_input: Detect whether the input gene expression data are valid

In UNDO: Unsupervised Deconvolution of Tumor-Stromal Mixed Expressions

Description

Check the input gene expression data to see whether they are nonempty, nonnegative, etc.

Usage

gene_expression_input(X)

Arguments

X	gene expression data matrix with row representing genes/probe sets, and column representing samples.

Value

If the input is valid, the output will be the same as the input; otherwise, if the input contains NA, the corresponding rows will be deleted. if the input contains negative value, the algorithm will stop and give error information.
