convert regex patterns to column names (internal)

An internal utility function that converts regular expression patterns used for quality control in single-cell RNA-seq analysis into standardized column names for Seurat object metadata. This function handles both single patterns and combined patterns with logical OR operators.

Usage

Pattern2Colname(pat)

Arguments

pat

A character string containing a regular expression pattern or multiple patterns combined with | (OR operator).

Value

A character string with the standardized column name derived from the input pattern(s). The output follows these conventions: - Lowercase letters only - Special characters removed or replaced with underscores - Common patterns mapped to standardized abbreviations - Combined patterns sorted alphabetically and joined with underscores
