+**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

+**Example**
+
+- input wiggle format file::
+
+    #track type=wiggle_0 name="Bed Format" description="BED format"
+    chr19 59302000 59302300 -1.0
+    chr19 59302300 59302600 -0.75
+    chr19 59302600 59302900 -0.50
+    chr19 59302900 59303200 -0.25
+    chr19 59303200 59303500 0.0
+    #track type=wiggle_0 name="variableStep" description="variableStep format"
+    variableStep chrom=chr19 span=150
+    59304701 10.0
+    59304901 12.5
+    59305401 15.0
+    59305601 17.5
+    #track type=wiggle_0 name="fixedStep" description="fixed step" visibility=full
+    fixedStep chrom=chr19 start=59307401 step=300 span=200
+    1000
+    900
+    800
+    700
+    600
+
+- convert the above file to interval file::
