You can import quantitative tracks in BedGraph (.bedgraph), Wiggle (.wig) or BigWig (.bigwig) formats. The BedGraph format is representative; it is a tab-separated file with four columns:

  1. Map name
  2. Block start coordinate
  3. Block end coordinate
  4. Value for this block (positive and negative floating-point values are supported)

For example, the given sample file...

1        3696        3714        2
1        3714        3747        4
1        3747        3765        2
1        3766        3804        3
1        3804        3809        8
1        3809        3817        9
1        3817        3839        6
1        3839        3840        5
1        3840        3855        6
1        3855        3861        1
...

...produces the following quantitative track:
