[galaxy-user] comparing data sets with different coordinates

Hello, May I use galaxy to do correlation analyses with two continuous quantitative data sets containing different coordinates (two different microarray designs)? How can I create sliding windowed averages for these data sets to accomplish this? How can I perform a correlation analysis with a wiggle and a bed (e.g., microarray data VS gene density). Would I need to do a grouping of my microarray data with another spreadsheet defining the window coordinates? Thanks, Dan
