What kind of analysis is practically done on GSE data files? I have a GSE data file in csv file format containing fields such as: ID, adj.P.Val, P.Value, t, B, logFC, Gene.symbol, Gene.title. In which adj.P.Val, P.Value, t, B, logFC fields being numeric. What are the factors I need to consider if I want to cluster the data only on logFC using K-Means clustering algorithm ? And first of all is it feasible to perform clustering on GSE data files ? If yes, what should be the approach ? If not, what different kinds of analysis can be performed on such kind of datasets ?

Following is snapshot of the data:
Have you ever used GEO2R? You can use GEO2R to analyze the data dividing it in subgroups (clusters) that interest you.
