如何使用 cytoscape 在有向网络图中识别或可视化节点组

Question

I have a network table containing three columns as indicated below in R code

data <- data.frame(from = letters[1:20], to= LETTERS[1:20],
                   group = rep(c("normal", "middle", "high","veryhigh"),times =c(5,5,5,5)))

I did export the data to Cytoscape app for visualizing the network. However, I tried a lot but could not able to make the following.

1. How can I give colors for the nodes in column "from" and column "to" and how I can differetly the nodes in the from column from to column?
2. How can I see the nodes of the four groups in different colors based on the group column in one network?

I would appricate it if some could give some tips here! Thank you!

Answer 1

I'm afraid I don't quite understand your question. Once this is imported into Cytoscape, you should be able to use the Styles panel to color your nodes using a discrete mapper. I'm assuming you're talking about Cytoscape desktop, here, right?
