hi @stepra,
We dont have much time to respond to all the questions on this forum!
There is no quick fix we can provide at this stage. One would be to play with the arguments var.names and size.variables. It will not be a deal breaker for a first submission of the manuscript! The other option is to extract the similarity matrix:
output = circosPlot(nutrimouse.sgccda, cutoff = 0.7, size.legend = 1.1)
output
And then you can use cytoscape or any other software to represent this signature as networks style.
