The genes data is a (num_genes x 4) matrix where num_genes is the total number of uniquely annotated genes. Column 1 is the gene ID, column 2 is the starting exon and column 3 is the ending exon in the gene. If Column 2 = 1 and Column 3 = 4, then exons 1,2,3 and 4 are inside the gene. Column 4 is the gene length.num_genes = 2Source
