Before revision:  For metabolic networks of URLanisms, relations changed for 58\% of the comparisons when a different definition was applied  .
After revision:  For metabolic networks of URLanisms, relations changed for 58\% of the comparisons when a different definition was applied . Values for the clustering coefficient vary with the ratio of isolated and leaf nodes which is critical for comparing networks. We suggest including ratio and definition in publications to enable comparisons across different studies .
