I am using stringApp on Cytoscape to generate STRING networks of proteins. I have 4 different protein networks that I would like to export out as PDFs, and later combine them together as one figure in Adobe Illustrator, but all the exported PDFs have different scales, which makes it hard to standardize the font, node and edge sizes.

I would like to know if there is a way to combine the STRING networks together in Cytoscape so that I can just outright avoid the scale issue between multiple PDFs.

Alternatively, is there a way to standardize the size of individual exports so that the scaling will be the same when I export the STRING networks on Illustrator?

I have already tried using the merge function but it just resets my manual formatting.
