Hi ,

I would like to plot a bed file with numeric values ( = bedgraph). My input data are : chr pos start end value ( value between -1 and 1)

exemple :

chr19   50906809        50907015          0.8173737057494912
chr19   50909381        50909562          0.2639404477044525
chr19   50909499        50909702          0.5421707627971464
chr19   50909697        50909863          0.7663584319162735

Hi there, the plot you have in your original post has the whole genome and uses points intead of bars. Would this possible to do in Sushi? I went through the pdf manual but I could not find the exact usage. Best

yeah but for ~100bp will you really be able to see a width of a scaled interval ? should be <1 pixel for a human genome.
