  1. CPU times (sec) and memory usage (GB) for approximate uQlust:Tree vs. full hierarchical clustering, obtained by using ClusCo [6] or MaxClust [22]. All calculations were performed on a server with 16 Intel (R) Xeon (R) E5-2680-0@2.70GHz CPUs, 132GB, and Linux version 2.6.32-504.1.3.el6.centos.plus.x86_64
