I know there are very nice tools like DAVID, GSEA, WikiPathways etc, for pathway enrichment analysis. Where they take bunch of genes as an input and produce a list of enriched pathways with some p-values.
My questions is, what if I have affymetrix probe ids, gene name and the expression value of gene in two cell types (say CD34+ and leukemic), and I want to look for the pathways enriched by these genes based on fold change between different conditions or cell types.
The data is in the format of log2 and the organism is human.
Could you please suggest a tool or a method to solve such a puzzle.
