19 This tool converts wiggle data into interval type.
|
|
|
20
|
|
|
21 - **Wiggle format**: The .wig format is line-oriented. Wiggle data is preceded by a UCSC track definition line. Following the track definition line is the track data, which can be entered in three different formats described below.
|
|
|
22
|
|
|
23 - **BED format** with no declaration line and four columns of data::
|
|
|
24
|
|
|
25 chromA chromStartA chromEndA dataValueA
|
|
|
26 chromB chromStartB chromEndB dataValueB
|
|
|
27
|
|
|
28 - **variableStep** two column data; started by a declaration line and followed with chromosome positions and data values::
|
|
|
29
|
|
|
30 variableStep chrom=chrN [span=windowSize]
|
|
|
31 chromStartA dataValueA
|
|
|
32 chromStartB dataValueB
|
|
|
33
|
|
|
34 - **fixedStep** single column data; started by a declaration line and followed with data values::
|
|
|
35
|
|
|
36 fixedStep chrom=chrN start=position step=stepInterval [span=windowSize]
|
|
|
37 dataValue1
|
|
|
38 dataValue2
