The windowing function is only applicable to WIG or bigWig files. Let's take this one as an example: http://chromozoom.org/?db=sacCer3&customTracks=http://chromozoom.org/docs/examples/Buhler_2007_dmc1delta_denoised_ratios_V64.wig
When zoomed far out, if you change the windowing function between min/mean/max, you'll notice the peaks shift up and down a little bit.
The concept is, whenever ChromoZoom draws a pixel, it has to combine datapoints that fit into the pixel, and this is what the windowing function is used for--do we draw the max of the data, the min of the data, or the mean of the data in the pixel.

Hey Matthew, we've actually been working on this feature but have kept it in beta while we work out the kinks.
If you want to give it a test drive, check out http://beta.chromozoom.org
You can load the other genome layouts on UCSC, an IGB custom genome directory, or a GenBank file. I might caution that not all the features work correctly yet, but would love to know your thoughts.

Thanks Leo! I'll take a look at that.
