Two questions - 1. When I call peaks with MACS on Galaxy I get different results than if I run MACS on my machine via command line. I'm using default parameters in both instances. 2. Are there any tools in galaxy for doing de-novo motif analysis of the peaks that I have called. If not can anyone suggest their favorite programs for doing so? I prefer a web interface but can fumble my way around using command line.
