Values File =========== An intermediate file created by the pipeline when "joining" the contacts between different species based on the orthology relationships. It is created by the script :doc:`join_pairs.py `. It is a tabulated-separated values file, usually gzipped. There is no header row. For each row, we have two species (named *left* and *right*), and four genes, two by species. The gene 1 in species left and the gene 1 in species right are orthologs, as are the gene 2 in species left and the gene 2 in species right. Then, the columns are the following: * the name of the gene 1 in species left, a string, * the name of the gene 2 in species left, a string, * the name of the gene 1 in species right, a string, * the name of the gene 2 in species right, a string, * the Hi-C value (*i.e.* the corrected and normalized number of contacts) for the genes 1 and 2 in species left, a floating-point number, * the Hi-C value for the genes 1 and 2 in species right.
