Thank you for the reply.
Yes, my header & chromosome was not right. Adding correct header & changing chromosome name from 'Chromosome' to 'chr' solved my problem :
browser position chr:0-4411533
browser hide all
browser pack refGene encodeRegions
browser full altGraph
# 300 base wide bar graph, autoScale is on by default == graphing
# limits will dynamically change to always show full range of data
# in viewing window, priority = 20 positions this as the second graph
# Note, zero-relative, half-open coordinate system in use for bedGraph format
track type=bedGraph name="Input" description="BedGraph format" visibility=full color=200,100,0 altColor=0,100,200 priority=20
chr 0 1 167.00000
chr 1 2 169.00000
chr 2 3 171.00000
chr 3 4 173.00000
chr 4 5 175.00000
chr 5 6 177.00000
chr 6 7 179.00000
are you sure
