Dear all.

The firstSigNodes argument in the function that plots DAG in topGO allows to control the number of "TOP ranked" significant GO terms that will be including in the DAG. However the problem is that parents GO terms are also included in  the final DAG. That fill the plot with nodes that do not add to much significant information. For example by selecting fistSignodes = 5 and ended up with a DAG with 48 nodes, and most of these nods are not significant according to p-value. 

It is possible to plot only nodes that surpassed certain p-value threshold?
