I have a set of ~60 differentially expressed genes and their log fold changes. Is there a way for me to visualize the network, but color the nodes based on their fold-change?

Thank you!

Please refer to stringdb package manual page 3 on wards (pay attention to the following line in page6):

example1_mapped_pval05 <- string_db$add_diff_exp_color( subset(example1_mapped, pvalue<0.05), logFcColStr="logFC" )

You can do this using Cystoscape for example. See this post.

If you just want to color the nodes based on their fold-change in just one experimental group, I think Cytoscape mentioned by Jean-Karim Heriche can meet your needs. But if you want to color nodes in multiple groups, I recommend you to use PPIExp. In PPIExp, you can color nodes in multiple groups. Here is an example: enter image description here
