"Nodes agglomerated based on co-occurence patterns"

[Patricia]

Hello all,

On the MED index.html result sheet the field "Nodes agglomerated based on co-occurence patterns" is left blank in my case. Does this mean that zero nodes could be identified based on co-occurrence patterns (= no significant co-occurrence patterns in my data) or does it mean that this analysis was not performed? If the latter, how do I make the pipeline perform this analysis? 

Thank you very much for your help.
