-The cooler [format](#schema) implements a simple data model that stores a high resolution contact matrix along with important auxiliary data such as scaffold information, genomic bin annotations, and basic metadata. Data tables are stored in a **columnar** representation as HDF5 Groups of 1D array datasets of equal length. The contact matrix itself is stored as a single table containing only the **nonzero upper triangle** pixels.
