+BigWig
+------
+
+    Input wiggle data can be in variableStep (for data with irregular
+    intervals) or fixedStep (for data with regular intervals). Regardless of
+    the input, the output will always in bedGraph format. bedGraph format is
+    similar to wiggle format and can be converted into BigWig format using UCSC
+    wigToBigWig tool. We export files in bedGraph because it is usually much
+    smaller than file in wiggle format, and more importantly, CrossMap
+    internally transforms wiggle into bedGraph to increase running speed.
+
+Please see `the manual <http://crossmap.sourceforge.net/#convert-wiggle-bigwig-format-files>`__ for more details
