gene_filter2: Second filtering step

In wikiselev/clustools: Tools for cluster analysis of single cell high throughput data

Description

Filter genes that would not contribute to clustering, because statistically they have a very low contribution

Usage

gene_filter2(d, method)

Arguments

d	Expression matrix with rows as genes and columns as cells
method	Filtering method. There are four options: "correlation", "variance", "variance_weight", "shannon_weight" or "none". If "correlation" is used a Pearson correlation value is used with a threshold of 0.8.

Value

Filtered expression matrix where statistically weak genes are excluded

Examples

gene_filter2(quake, "correlation")
