**Syntax**

This tool converts wiggle data into bigWig 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
