Hi Professor Chen,

I keep getting the following message "Spring(9170):null" no matter what I select as the criteria for bibliographic coupling. It seems that "Top N" is the only criteria the software allows me to select for coupling. I would greatly appreciate any advice you can provide on what should be done to generate clusters, and to view the citing articles. At the moment, I can only see the cited references on Cluster Explorer.

Many thanks in advance for your help,
Dave
