 This tool merges multiple BedGraph files, allowing direct and fine-scale coverage comparisons among many samples/files. The BedGraph files need not represent the same intervals; the tool will identify both common and file-specific intervals. In addition, the BedGraph values need not be numeric: one can use any text as the BedGraph value and the tool will compare the values from multiple files.

 This tool requires that each BedGraph file is reference-sorted (chrom, then start) and contains non-overlapping intervals (within a given file).
