Hi Galaxy dev team, I'm trying to the you galaxy server to do NGS peak calling: Tools -> NGS: Peak Calling -> MACS<https://main.g2.bx.psu.edu/tool_runner?tool_id=peakcalling_macs> Model-based Analysis of ChIP-Seq. However, the page won't allow me enter the input files: the drop-down selection box won't show anything when clicked. Same problem for the ChIP-Seq Control File selection box. Please take a look and email me back if problem is fixed.
