Please, kindly assist me in resolving the following problems urgently: (1) I conducted a proteomic analysis using the shot-gun approach, I have a list of identified peptides as well as a list of identified proteins and also a list of identified phospho-peptides as well as a list of identified phospho-proteins. Please, which of these lists is appropriate for uploading into cytoscape to build a (i) PPI network and (ii) a signaling network.
(2) I have been generating my PPI network with STRING and import into cytoscape for visualization and further analysis. However, I will like to import the text file of the PPI network which I downloaded from DAVID into cytoscape. Please, does any one know how to do this? Thanks.
