I need a few suggestions from Cytoscape experts. I have qPCR results (60 genes) with fold change and log value too, and I want to perform enrichment analysis (gprofiler and Cytoscape or any software you can suggest). I have never done that kind of analysis before. I was watching people comments and videos but still, can’t figure out how to put my data for enrichment analysis in Cytoscape and how to camper group vice. I have this kind of data; please advise me how I can proceed better way to analysis.

As the previous comment suggested, you need to first figure out what your question is. For example, say your g-B column represents a condition fold change and your g-E column represents some treatment condition fold change. And you're interested in seeing what terms best describe the genes where g-B is up-regulated and g-E is down-regulated. In Cytoscape, you would do that by using an app like the stringApp to create a network, then create a filter that would select the nodes of interest and then use STRING's enrichment. On the other hand, if you are looking to find enriched terms for a set of genes that have similar expression patterns across all columns g-B:g-E, then I think you'll want to use something like GSEA (https://www.gsea-msigdb.org/gsea/index.jsp), which doesn't use Cytoscape at all.
