wiggle_to_simple.py $input $out_file1
**Syntax**
This tool converts wiggle data into interval type.
- **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.
- **BED format** with no declaration line and four columns of data::
chromA chromStartA chromEndA dataValueA
chromB chromStartB chromEndB dataValueB
- **variableStep** two column data; started by a declaration line and followed with chromosome positions and data values::
variableStep chrom=chrN [span=windowSize]
chromStartA dataValueA
chromStartB dataValueB
- **fixedStep** single column data; started by a declaration line and followed with data values::
fixedStep chrom=chrN start=position step=stepInterval [span=windowSize]
dataValue1
dataValue2
