Does the windowing function work?
What is windowing function? It seems to me, the windowing function doesn't work. Can you make sure it?
I guess the windowing function is a normalization term based on maxmal/mean/minimal value of reads. Is it right?
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.
