Does the windowing function work?
Hi Support,
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?
Thanks.

Hi wchen,
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 fordo we draw the max of the data, the min of the data, or the mean of the data in the pixel.
Cheers
